thats great, I was just giving an observation.

They've done this to all 3 of the tunes ive seen...yours was the only one that was road raced...the other two were mine & Jim's car which neither were roadraced...its a blanketed thing they do in their tuning from what I can see not because you roadrace.

reread what I said...they only used the MAF for tuning...i didnt say they touched the o2's cuz in your old car scott they didnt...they didnt cut them...they still use them in your combo what im saying is instead of touching cot, pe, ve they used ONLY the MAF for tuning fueling. The O2's are still active which is why he was able to pass emissions in his case.

I have no doubt that you can coax more power out of it with HP tuners, you are good at it and its a better tuning program than ls1edit.  |
I honestly don't know if I could get more out of it...maybe it is maxed. I was honest with Chris in that his tune may be spot on and Im sure as hell not going to ask anyone for money just because. I've always said there are 100 ways to skin a cat, cartek has their way which in their little world might be fine & for some people as Marc stated its worked out great with their 8, 9, 10 second cars...for my car it didnt work for ****. Now knowing what I know I can see why. They obviously have a good business going, god bless them. I was just stating what was in the tune & how they do it.
