I could go search on other forums but I like it here so Ill see what you guys can come up with first.

got a custom one put on tonight. Hopefully it works over the 1200 miles I plan to put on it this weekend:happy2:

 

[rmallen30]

who did it and let me know what the diff is please

Gassers dont respond to tuning like the diesels do. So dont get your hopes up that your gonna start beating corvetts or some crazy MPG changes :thumb:

I need a freakin tune for my little 4.8

Actually the power is nothing to get excited about but you can tell it gained some snap to it. Most notably the shift points were changed for the better. But the best was we went from 18mpg highway to 22-19 mpg on the 3 tanks we put into it this weekend.
The tune was done by a guy here in town who makes turbo kits and does EFI tunes.
He goes by kbracing96 on several sites like gmfullsize, ls1tech and others.

anyway to get ahold of him in not looking for anything other than mpg 16.7 sucks
