Default 5.3 reduced engine power
Just recently rebuilt me 5Three and its got a 218/228 cam, headers, CAI, no tune yet but I started up for the first time and got that code. Before I rebuilt the motor I got this code and it was because of the ground on the battery, which was corroded, never had it again. I'm not sure what it could be now . NEED HELP GUYS

Have you clean the tb or maf? If not try that and disconnect. The battery before unhook anything

REP id imagine its a 2003+ truck.
Cam and no tune might be enough to throw it. What codes are stored?
