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!!
