Tried my buddys pamr-4bank Diablo file last night in my car and it felt pretty comparible to mine, he has a higher mph 120.7 with this tune than I do but he doesnt have my et (his best is 11.51) not sure if it would have felt better or worse after a few driving cycles compared to my current Diablo race tune or not. We are planning to swap tunes next time at the track and see what the hard results are, I have been wonderin about my mph for some time now and especially now that Blwn03's car is trapping the same in the 1/8 but is almost 4mph higher in the 1/4. My race tune has alot of timing (25.9) and an A/F of 12's up to 12.5 @ 6500, just wondering if a tune with a little less timing and more fuel would help my car out on the big end???? I also tried Broke7's tune in my car a month or so ago and we agreed my tune felt a bit better, something is causing my car to lay down up top compared to others still not sure what it is??? Any guesses???????
