why dont you get your head out of your ass and actually post something useful instead of bashing people. First you start by saying your a mechanic shouldnt you know how to do this sh**t. Then you go off saying that the pacemaker is just a dyno queen, WHICH your WRONG again. If you have nothing useful to post, then don't post anyhting at all. And if you want me to kiss Larrys as so more i will. He does great work with Z's (not that Rich, Z1 and Geroge don't just to name a few) but Larry is closest to me out of all the main Z performance shops on the East Coast. I trust him and I stand behind his work. Get a clue!
