Ford vs Chevy Build-up

HandOverFist · 04-16-2016, 08:49 PM

Arrived late at Bowling Green today and only got one qualifying run. The injector/MAF swap proved to be only a marginal improvement. First pass was a 13.56 @ 96.42mph. I glanced at the afr gauge thru the lights and it was showing 11.6...far from the desired 13.5 afr.

Before first round I pulled 12 percent fuel across the board and was going to lower the fuel pressure a bit, but it was already below 40psi. Next pass only improved to a 13.51 @ 96.80mph. I'm thinking the next time I have this junk out I will remove the controller completely and run it on the stock ecm for effect...just about out of ideas here.
