EFILive7 quick tune
Just came back from the dyno and first EFIlive7 session
Mustang Dyno (NOT Dynajet) - Mustang will read about 10% less than a Dynojet 246 (from what I've been told)
2004 Z06, 6040 miles, stock everything.
Baseline: 314.9 hp, 314.5 tq - car was running very rich (11.68 at +-5000rpm)
Best: 323.4 hp, 321.9 tq - After bringing AF to 12.75 across the board, advancing spark to 25
Delta: 8.5 hp, 7.4 tq
Was running really nice, and could have leaned out more, advanced spark more, but this was a really good first tune and I'm happy with the results
Approximate crank hp at baseline is 410 and at best is 422 with the above numbers.

I am trying to get him into a nice CAM (nothing radical), valve train and Headers that would be good for the SCCA racing
This was a quick tune and not making changes using LTFTs, or VE Table. Only changes today were for WOT where I got rid of a small knock. If we had more time I know we could have hit 430 no problem or more. But since he does the scca racing I wanted RELIABLE HP not DYNO Queen HP. He was pushing 25 degrees, and a/f hitting 12.9 set at 13 and zero KR.
Gotta love EFI V7 tuner, now when I change the PE VS RPM a/f ratio, and tell it I want 12.5, 12.75( rounded up to 12.8) or 13 it did just that. Doing the same with my GTO using Ls1edit I went throught 9 iterations that resulted in a/f doing everything but what I told it. What a difference. BIG Recommendation for EFI.
