I got my new tuned FICM and put it in it works great seems to be a little harder to start cold but way better response. I took my tuner off just to see how it runs stock and wow!! when i put my extream or insanty on it it runs better but not a whole lot. I think i have some injector issues from the lpop problems im just not sure is all i know is stock this badmotha fuc## runs way hard. Better then new by a long shot..I dont need a diff tune for the tuned ficm do i?
