Thanks for the good input, all.
The complication for me is that I have a low boost turbo (Protomotive Stage 1), 10% enlarged throttle body, cams, etc. It is at WOT, under boost, that I am seeing lean numbers (should be 10-12, I have 12-14.5). Max boost is 5 psi. We are going to look at several things on this, including the tune on the EPROM (Todd Knighton’s), but more fuel is needed and I’m pretty sure the injectors/fuel delivery could be a factor nonetheless. But we will go step by step.
