Thanks. It is 10.78:1 and runs fine on 93 octane unleaded. Once in a while, I give it a splash of Cam2 110 (1-2 gallons to a tank) just for the smell.

They don't run rich at all really if you think about it.

At 0 seconds 4200, it's only subtracted roughly .5 from the AFR, it only maxes out at the redline at -1.3 and subsequently drops to between .5 and .75 at the shift where it stays pretty level until 7-8 seconds in. It never really drops the AFR to a consistent 1.0 until after 8 seconds until it begins to add fuel until either A. the end of the run or B at 25 seconds which it drops the AFR to the 9's.
You have to pay close attention to what years you're referring to, because not every PCM is programmed the same, especially when you get into the 2003 and later models.
Thanks for the replies. I just got to work and honestly didn't thoroughly read all the replies, but wondering....to get around it, Can I simply steal some PE settings from a stock file on a 97-2000?

This here, is one of the reasons why some people tend to zero out the entire time table though 20 seconds.
Nobody in their right mind would stand in these cars for that long to begin with, if they want to keep their 4th gear.
But who am I to give advice? Stock tunes are good for 11 seconds in some cars. :P
Are you saying I SHOULD zero out the time table through 20 seconds?

I appreciate anything you guys can offer. Like I said, I just haven't used my HPTuners for any supercharged cars since I got it several years and 2 upgrades ago. When I got it, it was for my old 2000 Camaro SS and was the "serial port" version. Now, it is the MPVI Pro version, and I only really use the software for my personal truck, and here at work to get some of these turds through emissions.

In a nutshell, I haven't stayed very "current" with the software use since I haven't really had a reason to...hence the newbie-ish type questions.

Thanks..
