I've heard that you can't count on these programmers to do anything that you need to change the chip itself to get any results. Well this proves that wrong. Have a lot more power and zip though got my K&N and TB spacer at the same time still noticed the improvement.

It's a great product. I was able to adjust some parameters in my car to help it run smooth. What I love the most is that it can tell me codes if there is something wrong with my car which saves me a lot of money instead of going to a mechanic.
