Dyno of 224/224 114
I have a 2000 TA M6, last dyno I put down down 381/379 sae on a dynojet. Mods at the time were ls6 intake, headers, magnaflow catback, lid. But I noticed that the peak power was at 4900 rpms because I was running 15.8 af ratio. Since then I put some lanes true duals, ported thottle body, smooth bellows, UD pulley, and retuned.. what should I expect next go around?

Those are decent #'s for that cam. I'm suprised to see the HP & tq readings so close? are those hp/tq or just 2 pulls of hp? If they are HP/TQ, it seems like you are peaking too early. You need a good tune?

You could see close to 400rwhp if you added all those boltons and a tune. Your initial numbers are pretty strong considering you didn't have a ported TB or UD pulley (smooth bellows won't do anything powerwise).

Ok, I just pulled the dyno out, and it was mesured by speed, and cross matching it with my first dyno it shows 5.5k rmps is the point where the horsepower peaks and then drops from there. Peak torque was somewhere around 4.5k

Make sure that whoever dyno'd your car never touches it again. No tuner/dyno operator in their right mind would contiune to run an engine at WOT if the a/f ratio was leaning out as much as yours was. You're lucky you didn't lose your motor on the dyno.

Yes I know.. it was done by a company called JMS in alabama. The first run he noticed that it was lean, and the second run cut it off early... but it still hit right under 15 on the second run.

Come to find out the reason it was leaning out so bad was that my injectors were running 130% duty cycle. I threw some 30lbers in there and if I remember correctly they were running 98%. And I know there was no vaccum leaks, and the pump is strong so Im not sure why its takin so much fuel.
