With the 130mm rod (-5mm) and 9mm more stroke (+4.5mm throw) the piston sits 0.5mm further below deck than a stock m20b25. It’s a good idea to machine a bit more off deck or use thinner gasket to optimise CR and squish
Hi Jon, I’m running this exact setup in my 88 convertible. Pulls like a train, but still running the stock 2.5 ECU and I always feel like there’s more there to give but not sure how to unlock it. Any hints on a better ECU option for the stroker?

I have heard excellent reports from Sssquid chip tunes. If you aren't already running a 272 cam you are leaving a lot on the table as well.
