power programmers??

[pwrjnky]

I just bought my 2005 yukon Denali 2 days ago and was wondering if any of you were using power programmers? Any good/bad? Experiences? If you need to know...I have the 6.0 motor. I'm curious because I pull a snowmobile trailer in the winter and want to get a little better gas milage and less downshifting while in drive.

love it

i have a 2007 tahoe with a 5.3 and i put the edge display in mine. i absolutely love the thing. i didn't notice much of a change in mileage, but the power difference was obvious from day one. and that extra power sure made it smoother when i pulled a trailer. for 450 bucks you cant go wrong!
