I installed a cam (specs in sig) and have been running it for about 6 months now. Its been running on the stock computer for the whole time. I recently had it checked for codes and its been having random misfires on all cylinders. Chevy says they want to bring in someone to look at (and most likely charge me an arm and a leg to simply tell me its the cam) and fix it. I am hoping it is simply a computer problem. I'd be much more willing to shell out the money for a tune if it will fix the problem. Should i just take my truck back and wait a week for the new tune or let chevy try to fix it.... Im betting on the tune right now. But i want opinions from people who have cam'd and have had it tuned. Have your tunes solved problem with it running? Any info would be appreciated.

 

Most aftermarket cams cause random misfire codes. As long as it's running correctly they're not to worry about.

 

Have it tuned. MTI's doing a gp...
