nelson performance?

[08vortec4.8]

looking for a little bit of extra power on my truck. has anybody put in nelson performance pcm and tcm in their truck? was it worth it and what MPG gain did u see. also have you had any issues with it?

thats a lot of hassle for better mpg and power just get a programmer if you want to go that route. and there are lots of other things you can do for better mpg and performance

More power and better mileage don't go hand in hand. Lots of claims about better mileage but little proof to back it up. All the claims are "hearsay" and hearsay is no proof on anything.
