Great product that does what it says. My car is auto and the 93 firm shift setting grabs 3rd often! Has bumped up the fun factor and it never gets old!

Had issues with first module sent (engine light kept coming on a lot?), but after Jet Performance expeditiously sent a replacement all has been excellent! Increased everything across the board as JP described to very noticeable levels! Now my GT is doing what it was designed to do, PERFORM! NOTE: Although I was skeptical at first changing from 87 Octane to 91 Octane, the REAL benefits came using 91 Octane as Jet Performance recommends!! A REAL THUMBS UP PRODUCT!!
