First time at the track with my IX. So close to 11's!
I have a mail-in DynoFlash for 91 pump gas. I usaully have it set to spike 21 and hold 19-20. I used race gas at the track and turned the boost up a little to spike 23 and hold about 20. I wasnt sure how high I could raise the boost since I dont have a custom tune yet. My a/f's were about 10.5-10.8 when I turned it up. Another thing is with my Forge mbc it seems like I have to turn the knob a lot just to get the boost to raise 1psi?
He was faster at the 1/8 mile time on the 111.51 run then the run with the 114.82 so something must have happened...you hit the rev limit in 4th...this is a fraction of a second difference but 3 mph difference. Do you think you shifted early at all?
Possibly. It went by so fast it was kind of hard to watch everything.
