New best after dyno tune!

Bryan of pcmforless tuned the car to only 355 rwhp, but he said if he could have locked the converter it would have been right around 400 rwhp. Anyway, after the tune I went to Rockingham ran a 11.65@ 114.04mph with bad air. It should easily run in the low 11.5's high 11.4's in good air, I'm happy to say the least. Also, I won the 1/4 trophy class, so not only is the car faster it's consistent to.

Nice times. Mine is not running great right now. I swapped cams, converter and went to a 58mm throttle body and one or more of the three is killing my bottomend under 4krpms. I have a tight 3800 n2o converter and the car bogs out of the hole. But I am also running 3.42's so I have some work to do. 11.92@113.8MPH.

Youre also running a standard which usually trap higher.

If you dont mind me asking how much did you gain on the dyno with a tune?

After the first pull Bryan found the car wicked lean, so he threw a bunch of fuel at it to get the A/F ratio down. The next pull it picked up 40hp at the peak 45tq at the peak and 50tq in the mid-range.
