What a BIG difference. The response of the gas pedal is crazy. Crazy that it doesn't come from the dealer/ factory like this. It's insane that you have to drop more money to get your truck performing as it should. I coupled this with a cold air intake, and I gotta tell you honestly, I'm excited to drive anywhere. Small trips to the store, to work, and long distances are pleasurable now. I highly recommend this product to anyone.
