[QUOTE="D-Con, post: 5915834, member: 40944"] I just installed a o/r x-pipe and FR-500 exhaust in my otherwise all-stock hardware Cobra. Before I did the exhaust I had downloaded one of the standard programmed Predator tunes for mildly modified stocker, or whatever they call it, and also turned the rear o2 sensors off. It seemed to work fine with the stock exhaust on it. Now I have a bad sputter at the top of 1 and 2 gear (didn't try for 3). It doesn't seem to have a problem if I just mash the throttle in a higher gear but I didn't try to run it all the way out like that. :shrug: I cant tell if it's fuel or spark, but my guess is fuel. I just remembered I should have unhooked the battery to let the computer re-learn, but haven't tested it yet. Could that be all of it? I'm a newb to Cobra tuning...help? [/QUOTE]
