I have a question I have a new 05' Duramax which programmer box would be the one to buy? I do a lot of towing with a 40' enclosed gooseneck trailer.
I am deciding between the Edge juice w/ attitude or the Bullydog. Before I install it, should I put a few thousand miles on the truck before hand for a break-in period or it's not required? Thanks

Had both. Prefer Predator for the LLY. Also some new stuff coming out. Might want to wait a little while, then decide.

New stuff is coming .....might be worth the wait

edge has some serious problems with the lly 05 imo

i think the predator is a great programmer. i put down some great numbers today at the dyno run. each tune seemed to do as it said it would. my best was 339hp and 700 tq on winter fuel. also the motor was reall hot. i probly wold of done allot better if it was a little cooler.

What do you guys think about the Hypertech Programmers? I am in the market for this summer?


Thanks
