I had used the Preditor programmer on my 03', and it worked good, then I had the computer reprogrammed with LS1 Edit and it was even better.

I read about the efilive on LS1 tech , is your truck n/a or boosted?
What did you change with programming and what did it do to your truck ?
Thanks for respons.

Normal, exhaust and Volant air intake, runs great, more power by far, although I have not had it back on the dyno after the mods and tune. Fuel mileage about the same in the city, better on the highway 18-19.
