Well, I decided to update and reprogram during my lunch brake. I've only put about 10 miles (maybe) on it and have only tried the 87 performance tune, so far. The engine seems to idle much smoother. Before it had kind of a "lobe" to it. It wasn't a bad at all, just noticeable, the engine would
slightly rock the truck when stopped at a red light, it no longer does this...it's nice a smooth. So far, the sputtering problem has not occurred, it runs very much like the Edge canned tunes did. My only concern is if you leaned out the A/F ratio any. The reason why I ask is in the short amount of time I was able to drive it, it says that its getting 18.2 MPG, and that was with my playing with it and running it hard, good amount of WOT and downshifting it (I was trying see if it would sputter) when coming up on red light and such. I do know my truck very well and my old custom tunes very well and it has
never showed me 18.2 MPG before, I guess I just want to make sure that it's not running lean. Besides for that one concern, so far so good... It's running great! I'll get some more road time with it, and try out the towing tune as well. I'll try out the 93 tune after I use up my tank of 87. I'll keep you posted!
