Very noticeable difference in power! And I noticed fuel economy is better also when I keep my foot out of it lol! And it fixed my transmission “gliding” between shifts! Definitely recommend

Do not buy If you have have a charger or 300c 5.7l all options do not work at least for my car! But over all its a good product.

Really wakes up the 5.7 hemi, should've came from the factory like that. Highly recommended, priced to beat the competitors as well.

This is a great tuner for my 2008 f150 4.6, for the price. It gave me more power, the trans shifts firmer and the throttle lag gone.
