I guess everyone's entitled to their opinions.
Personally, I'm placing my order for a PCM tune this afternoon.
I have read the threads on PCM for Less on Elcova and on
Hummerforums.com - EVERYONE that has gotten a tune has
been happy with it. There was a major skeptic on Hummerforums
that I understand in the beginning gave major flack about this company
and its tunes, well now he has one of their tunes and is SUPER HAPPY with the tune.
I'm putting 315's on my truck and this tune will do what I want it to:
correct the shift points, show the correct mileage on the speedometer/odometer and give me a smoother ride. I will also get some other benefits as other posters/threads have mentioned, for me that will be great!
ChevyHighPerformance and others with the technical knowledge that I don't have, have looked into this company and are satisfied - so that is good enough for me for what I need done.
If you don't like or care for the company - then don't buy their product.
