I actually had that too! Plus the beads. I can say I haven’t had any rfi issues with the sniper 2. Some people have said they had to go to a plastic air cleaner stud. But that wasn’t an option for me due to the blow thru set up.
On the sniper 1 units we ran into issues with them getting the rfi from the air cleaner housing transfering it down the center rod. We started making the center rod out of delrin and running double gaskets at the base to stop it. Fixed several this way. There is also shielded covering you can buy from Mcmaster Carr. It's expensive but will take the interference away.
As someone who has installed a sniper 1 in the last year. Mine has had zero issues out of the box. But ive seen so many struggling with the ecu resetting or cutting out. So i agree holley should have a better quality control of their units. I will probably do a sniper 2 on my other project im building. But good breakdown!
@@dirtytruckhotrodshop7829 if i had to wager I’d say theres a crappy solder connection or a cheap chip in then that is the cause of issues like yours. By the time holley realized it they are underwater in customer service. Hopefully the 2 is a better quality unit. Only time will tell
I actually haven't had much trouble with mine with RFI. I have a 94 GMC with a 454. OG sniper with hyperspark. Only problem im having now is my fault I think. I put the o2 sensor behind the connection point on the header and i just cooked my 3rd one. I'm in western Pa.
It seems some people never have any issues. I feel like gm’s had less issues due to distributor location vs fords. Moving it to the side was a solution. I’ve heard of lots of o2 sensor issues too.
I've put off running this on my stock IH 345 (currently a 2bbl holley street avenger 2300).after hearing about how many dead ECUs and issues they've had. Would you say now is a good time to finally pull the trigger on an old stock IH v8?
If you are buying one so far the sniper 2 seems like the best bet. There is also ace’s efi set ups. No personal experience but I see people having luck with them.
cool cool. figured out the 347 soon after. started watching your other vids :P i did similar with my turbo setup. ebay shorties flipped forward, chopped the merge and welded on v-bands, then built the crossover and up-pipe. get to do it all over again soon with the 408w. how's that sniper 2 treating you so far? it doesn't have any sensor inputs does it? any programmable outputs you could use to setup the boost control? i run a 1250 super sniper now that has the extra 3/3 in/out.@@dirtytruckhotrodshop7829
ok, ya that's what i kinda figured. was just update base sniper. kinda hoped that had added some inputs/outputs to it and would increase the amount that came on the future "super sniper 2". i'll be moving on to port injection anyway, but just thought it would be nice for others. being able to add fuel pressure sensor is huge imo. @@dirtytruckhotrodshop7829
we have the sniper 1 on our 454 powered 38 chevy truck in uk been messing around with it for 3 months with multiple problems ie new display 2 pressure regulators blocked injectors from the factory it still dont run well glad the sniper 2 seems much better, always loved holley products but not the sniper 1
I've been running a Sniper Stealth on my Windsor since 2022. I chose that variant because of everyone having issues with the regular sniper (especially on Fords), and because I wanted the 4150 carb appearance. I haven't had a single issue with it. I'm running the Hyperspark distributor with a 6AL-2 box, and Ford Racing cut-to-fit plug wires. My alternator is a Gen3 200-amp, and out of an abundance of caution, I added an external ground cable. I think Holley should have just stopped selling the square sniper just sell the stealth instead of coming out with the V2. Just sayin...
It does seem that anything with a distributor in the front was more problematic. I’ve gotten lots of messages about guys with other engines having the same issues too. This sniper 2 has been good so far. I went to great lengths to make the first one work and I’ve installed a lot of stand alones over the years and really never had issues. So this was a surprise to me.
@@dirtytruckhotrodshop7829- Someone on farcebook mentioned that if your harness wires cross over the spark plug wires (a common situation for GM guys), that is another common source of RFI as well.
How do you think this system would be on a 355 cu in crate motor from Jegs. I plan on running EFI for my 72 Blazer. I just want it to drive and be reliable. Naturally aspirated, pump gas
DEPENDABLE >>>>>>>> Swap to HOWELL EFI it's ALL PROVEN GM technology & the company is built & run by a guy that actually worked in the GM engineering department WHILE the system was designed & used in production @editrento1
It’s sad how inconsistent the sniper is .. I have a good one running off Hyperspark .. works great on my 67 Camaro with a 383 stroker .. it’s -5 Celsius here in Canada and it runs great even now till the snow comes !! But if I ever need to I’ll upgrade just cause
I see lots of people with the same issues. I really think it’s just overly sensitive. The sniper 2 seems to work great so far. Holley needs to get the link cable done and the Bluetooth module out. I also wish it had more inputs and outputs.
@@dirtytruckhotrodshop7829 no doubt it’s an improvement just simply the ECU quality .. I wonder tho if someone had a side by side comparison of both units functioning well if there’s any real world difference .. !?
I think the xflow would show a power gain over the sniper 2 because of flowing more air. But that probably depends on if your engine needs or could use the additional air flow.
I’m from pa also lol👍 I bought a car with the sniper 1 original unit I want to get sniper 2 or just go to a carb. Is this unit reliable in your opinion I know it hasn’t been out long…
So far it seems to be! I think it’s much improved over the first get sniper! I’ve only put a few hundred miles on it but the first gen started acting up quickly and so far so good. Are you having issues with yours?
Yes with my sniper 1 I hate the throttle feel so stiff like you can’t just lightly push throttle… anyhow I’m having hesitation when I start off the car wants to die if I give it any throttle when taking off till I get to around 2,000 rpm.. or when I come to a stop and let off throttle it wants to die n cut out basically hesitation problem. Then sometimes it’ll run out nice once I get into higher rpms. The kid I bought it from was running stock 30 or 40 psi pump. So I put in 100 psi pump. It runs a little better of course it has built in regulator I was thinking iac valve or something I’m not messing with it though just upgrading
It's still not plug-n-play and their customer service still sucks if you have less than 1K CZcams subscribers.....The ECM is still part of the throttle body instead of separate so you can put it in a cooler location and when you have to send it back for repair, your car waits weeks....I'll try the Killshot before ever considering a Sniper...
There are definitely some downsides to the first gen designs. The second gen seems to address some of them. I actually was in talks with aces about a test unit and had downloaded the software. But then they kind of disappeared.
I also just switched from the sniper to sniper 2 and Agree Summit has been great .
Hopefully the sniper 2 is a good experience for you! So far it works much better than the previous version.
On my 70 Mach 1 - I used faraday tape on sniper wires to eliminate EMI.
I actually had that too! Plus the beads. I can say I haven’t had any rfi issues with the sniper 2. Some people have said they had to go to a plastic air cleaner stud. But that wasn’t an option for me due to the blow thru set up.
Nice video thank you. From what I seen is you have to have 50k or more subscribers for Holley to answer phones...
I’m thankful for summit racing that’s for sure!

I’ve read about people doing stuff like that. The sniper 2 is still working great for me. I’m out of fuel with it but it’s functioning well!

Mine initially was running great but then one day it just decided to act up.

I agree. Even summit told me they had seen a lot of the same issues!
I never knew why they didn't shield better. I bent a copper plate between my FiTech and my Ford 460 distributor.
Seems that’s a lot of the issue!

nice shed!!!!
Thank you!
stumbled across your channel. good looking truck. sweet setup you have. what engine/turbo setup you running?
It’s a 347 sbf, with a semi custom turbo kit. I used one eBay turbo header one eBay shorty flipped forward and built the rest. It’s a 76mm turbo.
cool cool. figured out the 347 soon after. started watching your other vids :P
i did similar with my turbo setup. ebay shorties flipped forward, chopped the merge and welded on v-bands, then built the crossover and up-pipe. get to do it all over again soon with the 408w. how's that sniper 2 treating you so far? it doesn't have any sensor inputs does it? any programmable outputs you could use to setup the boost control? i run a 1250 super sniper now that has the extra 3/3 in/out.@@dirtytruckhotrodshop7829
The sniper two really doesn’t have much. It’s basically like the base first gen sniper. You can set up a two step. So far it’s working great though!
ok, ya that's what i kinda figured. was just update base sniper. kinda hoped that had added some inputs/outputs to it and would increase the amount that came on the future "super sniper 2". i'll be moving on to port injection anyway, but just thought it would be nice for others. being able to add fuel pressure sensor is huge imo. @@dirtytruckhotrodshop7829

I agree! The sniper 2 is still working well for me. I know a lot of issues are user related or installer caused but a lot aren’t either.
I've been running a Sniper Stealth on my Windsor since 2022. I chose that variant because of everyone having issues with the regular sniper (especially on Fords), and because I wanted the 4150 carb appearance. I haven't had a single issue with it.

I have a Sniper 1. No problems. I must have got a good one.

Also summit only has 2 snipers left in stock not sure how that can happen already but oh well lol
It’s still noisy ?
I think the 1st gen snipers just had issues.
Looks like they just took everything from the Atomic 2.
I’ve never had my hands on one to know. If someone wanted to send one I would gladly do a comparison.
Freakin SHY NA built and or sourced crap, I've read SO MANY issues with these setups
Yeah a lot of people have a similar experience and it’s a shame from a big name like Holley.
Was thinking of getting Sniper 2
Now I don't know
It's still not plug-n-play and their customer service still sucks if you have less than 1K CZcams subscribers.....The ECM is still part of the throttle body instead of separate so you can put it in a cooler location and when you have to send it back for repair, your car waits weeks....I'll try the Killshot before ever considering a Sniper...

I have 1st gen sniper - works great, but I read, re-read, and followed the installation manual.
