I just put my tune in this morning from Jesse and I can tell a slight difference over the HPIII but not that big. But when you hit the Tow/Haul button you can diffently tell something is going on. My SES light did not come on either. I just got off the phone with Jesse and he said to get the relearn done anyway. It will help it even more. My truck does seem to be smoother, and I can turn over the 20's a little better than before and that is with just 50 miles a racked up this morning. That dude is so smart if you get a chance talk to him he will blow your mind with the stuff he knows about these computers.

 

Yea tune is good, but i was expecting a little more, i guess ill get my relearn tues and see if it makes alotta difference. It still feels doggish until 3 even with 100% removed.

 

Jesse seems to tune for top end. I notice a my truck is a little doggy down low, but the top end is spectacular....... Just depends on what you want.

 

If you have a scanner with logging capabilities, do a few runs after the adaptive learning cycle has taken hold.

e-mail the logs to Jesse and he can then fine tune the PCM for more power where you want it.
