Definitely made my car perform much greater. Love the added power and firmer shiftpoints. Can't go wrong with this one.

I initially had difficulty installing the performance tune on my vehicle but I suspect the cloud service was down. I later was able to add the tune and it was quite simple. I immediately noticed a difference in acceleration and an improvement in fuel economy. I am very pleased with this product.
