MPG have you guys gained by going with your aftermarket computer programmers? what type do you run? are you satisfied with the product you bought? would you recommend me to buy it? My dad has a 03 K3500 with the LLY engine. we will be doing alot of towing so we would like some extra power. i would like to know which is best, or offers the most for the money.
thank you in advance

You can see my mod list below. I am totally happy with all I have done and i am looking to do more. I just took the edge off and went to a predator. Mileage seems better but I am not sure yet. The power is a little less but I think the mileage will make up the difference. hope this helps.

FYI....Loose your kitty and you will be impressed!!
