Just added the Hypertech today on my truck. My only other mods are a Gibson single out catback.

So far I am pleased. Not that I had a problem before with lighting the tires up with my Z71 but today it just completely ripped 'em through an intersection and then proceeded to chirp the 1-2 shift....that put a smile on my face. I haven't checked too many other things since it was a short ride home from work, but I plan to tonight.

It's hard to tell how close I am getting to the rev limit. I set that to 6K and the 1-2 shift at +3. The truck is actually back to shifting where it used to on the tach before I installed the exhaust. It shifts right there, sometimes I feel the tq mgmt kick in and sometimes I don't.

Anyway, I guess I'll play with the shifts and maybe the rev-limit a bit but so far it seems to have made a nice difference, even down low where the truck was really lacking grunt. <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />

 

Are you from St Charles? I just sold my HPP3 to a guy from there.

 

I'm quite a bit north and east of St. Charles so that wasn't me. Was it someone on this board?
