I would also take the 3.4 pulley off until you get some exhaust mods, with headers and a 3.4 I still was gettin 5+kr on a intense's tune at the time.

Find someone in your area with a tuner.
He got 3 PCM's from them when he first bought his car....and they were all stuck in "read/write" mode. He didn't know much about the cars when he bought the pcm. When I looked at the scan, his spark tables were set entirely too high and his fuel was set to a lean AFR command.

The picture doesn't show the true damage, it spiked the fuel curve, and broke the skirts off of the piston. When he finally demanded his money back after the last one, he had to get really crappy with them to get the refund.

Now granted, this was back when they first started doing their own tunes, and in all honesty should not have been selling them just yet. Now they may have gotten better, I'm just not a fan of their PCM's.
