Is there a programmer out there that will give me a substantial horsepower gain without voiding the warranty on my 08 6.7cummins. Any help would be greatlly appreciated.

 

if you worried about the warranty, dont do anything to it, you'll sleep better.

otherwise dont go over 60 hp or so & keep it easy on the torque...

 

the MP-8 by ts performance claims to give you 100 hp and is said not to leave a footprint on the Comp. i have it and i know a few other that have it, i can tell a big diff. that with my edge WOW it has some kick to it lol

 

There is no programmer that will not void your warranty... I have yet to see one that is totally undetectable.
