Regarding your VE table I’ve found that once in boost my VE numbers don’t change all that much from 3psi all the way up to 15-16psi. Fuel flow obviously changes but the % doesn’t. There may be 2-3% difference between low boost and high boost for a given RPM. maybe that will help you/give you more confidence when you make your fuel map. Also 11.0 target seems really rich to me for 12psi. I target 11.5 at 15psi on E non intercooled.

Thanks! My VE table was pretty close at lower boost, maybe a point off but I’m being more conservative in the upper areas where I’ve never taken the motor before. I target 11.2 AFR at lower boost and then 11.0 up high to keep it on the safe side. Once I get the VE table dialed in I might lean out the AFRs a little. This is a 10.5:1 motor also.
