I am faster than the GMPP tune I am sure, I had more HP with the original race tune, that was about 20 tunes ago. I like the tune I have now, it has a ton of low end, I don't know how aggressive it is, same one Joe has, I can come off a stop take it to 6000 rpm and sit and spin the tires forever, it doesn't hook up until I back off or shift. I hope Lyndon can find some, I found them for him if that tells you anything.
