Little skeptical because of the price. I did do an AEM cold air intaike for the turbo first. Then I installed your chip. I haven’t even gone the 50 miles needed to complete the programming. However, my front wheels spin in 1st and 2nd gear! The difference is quite noticeable. I am actually surprised and impressed. I know the intake added some umph to it, but man! I am super happy so far with my $209 purchase! It is worth the money, I promise!
