Not happy with it. Had to send it back. Too many errors with it installed in a brand new vehicle. I'm buying a tuner instead.
The BEST Tuner Available!!!!

Compared the fashpaq tuner to others on the market and this is the best product for the price! Does it all! AutoAnything has the best prices than their competition by far! Great job guys!
Waste of money

Haven't seen any improvement at all in fuel economy or extra power. Don't waste your money. This is on a Chevy Silverado 2010 5.3L
