You need a tune. And where are you located ?? Then maybe someone could recommend a tuner.

U could always do a livernois tune via hptuners. Or go onto grrrr8.net and visit the regional forums for tuner recommendations in your area

That doesnt make any sense... Livernois locks their tunes rendering HPtuners useless.

Livernois can setup a tune for HPT, at least they told me they could over the phone a year or so.

If Ed is the closest to you then there are a couple of tuners in OKC that can tune via HPT.

I'm very happy with my Livernois tune, curious as to what went wrong with yours?

Most guys with the basic tunes are, its when they get into a heads/cam/converter, etc.. car that issues pop up. A few people have had to switch tunes from them to get their setup correct. I think they do great mechanical work and I'm running one of their cams, no complaints there. But as far as tuning my trans tune was jacked, my engine would self rev/drive, idle surge like a mofo, hard starts, and was down on power big time.

Stock MAF is fine... especially at your power level.
