The results, it dynoed 406.16 RWHP and 370.52 RWTQ on a Dynojet at Abel Racing. Dyno sheet is posted below. Donno how well she did compared to others but I can't complain.

The the future i'd like to go to an SD tune to get rid of a few cold start quirks prob a 2 bar setup so i can run lower fan temps since she runs 185-190 degrees. Not sure if I should play around with gaps or not on the plugs. Prob add a catch can. Eventually i'd like to do a Fast setup and maybe some heads.

Are these unlocked dyno numbers? Pretty good for a stalled auto. Hows it drive. I got one of Eds cam going in my new motor.

Seems strong.

Looks good. Built a few 05/06 stalled gto's like yours. The unlocked runs murder the dyno numbers.

Feel like an idiot but are you talking about the converter being locked or unlocked? I know when he dyno tuned it he didn't do any tricks to the trans to keep it in a certain gear or anything. He just started it up and gave her hell. Think he dd the WOT part in third gear. I have a couple dyno videos on my iphone. Now to figure out how to get them on here.

As for as how it runs and drives, it drives great! Can't even tell it has a stall honestly. It could easily be driven daily other than th rough idle which doesn't bother me a bit. :-)

Only quirk is starting it up especially cold I have to hold the revs to about a grand for about 30 seconds before she'll idle on her own. I believe alot of that is the MAF and the Varram. From what i've heard on other GTOs going with an SD tune cures alot of that. Plus if I go to a 2 bar map i can adjust my fans sooner than 194 degrees.
