Also, another thing I've noticed with my custom tunes is that the truck isn't very "spunky" at all between 0%-90% throttle (closed loop, I think), but anything between 90%-100% throttle (open loop, I think), it is a completely different truck. It's a complete night and day difference. If that is the case, is there a way to make the truck run "open loop" (I think)... The difference is seriously like comparing a Yugo to a Ferrari. If you are driving and are say at 90% throttle and the truck going along, If you push the throttle just a bit more it wakes up and pushes you back into the seat, and the RPM's shoot up FAST, but 90% throttle and less feels very much like the stock OEM tune...
I hope I'm explaining it well, it's kind of hard to describe I guess... I hope this info helps out with diagnosing what might be the problem...
