I changed to load indexed speed density and it runs great now. The engine builder had the alpha N tune all screwed up it only worked well at wot and high rpm. Fastman EFI did the new tune and it is really good fuel air ratios are right on for 114 fuel and it starts right up with out touching the throttle. I could not be happier with it, FAST man is about my age and really knows his stuff he has been tuning for years and knows both software and hardware. He also is an engine builder and Top Alcohol drag racer. My system is a FAST XFI 2.0 with traction control. If I had it to do over again I would buy the Holley port injection system because their self learning is so good.
