I also wouldn't trust those #'s. The dyno pull should have been done in 3rd gear(locked in gear with the converter locked as well). That is the correct way and if done correctly there should be no spikes in the graph. I would find a different tuner just to be sure.

That's the way mine was done.

That's the way most auto's are done. If he was "auto-shifting" during the dyno then he's a jack ***, and you should never go back there again.

he just put the damn thing in drive and punched it as far as i could tell..........when it would shift it would screach them on the dyno, so i guess that would explain the spikes....but when he was telling me about my numbers he was reffering to the line of the graph where the car was in 3rd gear so i guess it makes sense.....the shop is the best around here and its car ( KB supercharged 05' GT) is being featured in the next issue of Muscle Mustangs and Fast Fords, so they kno what there doing it seems
