I got my HPP3 in the mail the other day, and i was wondering what you other 4.8's set everything at? I'm running a 100 shot of N2O if that makes any difference. What did you guys change the shift points to or did you even change them, and stuff like that? All i changed was that i put the rev limiter at 6200, firmed up the shifts, raised top speed to 128, and raised the octane for when i dont run nitrous.

 

Raise the shift points to 1-2 +4, 2-3 +12. It works the best this way for the 4.8's.

I have a 4.8 and a HPP3 and found that with a 1-2 shift raise of +3 and 2-3 +11 and 3-4 +5 works great! 1-2 shift is around 6100 and with my setup it barks the tires. Just thought it might help a little. <img border="0" alt="[Burnout]" title="" src="graemlins/burnout.gif" />
