I have procede for a while and I am debating whether I want to trade my upgraded procede for my roomates COBB. He had to uninstall it from his car for service and I removed my procede today to send it off to be upgraded so I figured I would install it on my car to see how I like it.

Install went fine, I let it read my car to make sure I put the correct maps on and away I went. Well as soon as I got out on the road the car felt completely different. I let it warm up while putting around, every know and then I would give it a little just to see and damn it felt really good. Now that it was warm I got on it a little and the low end power is insane, but as soon as I got up top it misfired bad. I had to turn the car off and back on to make it go away and it did it again. It is doing the exact same thing it was doing before I changed my plugs on my procede. Any ideas on what I should look at?? I know for a fact the car is making more power b/c the clutch slipped in 4th and it has never done that before. Any help will be appreciated, I am not so knowledgeable with tuning and I am a complete noob to COBB AP.
