So people if you get one through three stages you want be disappointed ! Well people like they advertise that it is no gimmick, well it's not I got a stage two for my 2014 Silverado and another of the same for my son , he has a beautiful 2011 black SS Camaro that still has under 50.000 miles on it and you can tell the acceleration in both his and mine such a big difference! That is what I like about the chips there is no hesitation anymore and when you are rolling down highway o yea and hit it around other slower traffic big difference. Now as far as gas mileage well I think it is about the same that I was already getting ,but I am very happy with them . I have got two other friends to get them and counting . Alright Smarttune performance chip manufacturer all that I put in this review is true and very happy. I should get a stage three for all the sales I have sent your way lol .

It cost me a $200.00 repair bill It cost me a $200.00 repair bill for my 2007 Cadillac Escalade. The performance chip interfered with my EBS and Stabilitrak system. It affected my ride, and my braking, and after taking it off and throwing it away I feel like I'm riding in a completely different car. Whatever difference it was to supposed have failed to materialize after 1,500 miles.

They change their website page to try… They change their website page to try and hide their identity because so many people were having problems. Look at some of the comments the way they talk about their customers they call one guy troll. He’s not the one selling products performance chip tuning is a rip off and the people that work here are just as bad, they don’t mind stealing your money
