    Exhaust cam is off -3.8 degrees

    According to INPA, my exhaust cam is off -3.8 degrees. What hardware other than 6x 07129905536, 07119913589 should I purchase, to complete this work? thanks

    whoa whoa whoa chill down there, thats just the adaptation the DME has settled on for best performance.

    Are you rebuilding your engine or experiencing any problems currently?

            why do you need to replace those bolts? For the cam sleeves bolts, just clean the threads good and aplly medium Loctite on threads.
            The code says the EX cam sensor is bad so replace it.

              I'll go take it for a drive soon, and I'll come back and post all the codes. We can see what everyone thinks!

                You are still within the adaptations of the DME, here are mine after being super anal about timing the cams.

                Also, do you by any chance have a CSL tune and not account for US spec cam offsets?

                  Custom Dyno RKtune.. I just drove it for over an hour and this is all that showed up, P1448 and P0443. Those are from my evap tank/purge delete, they don't matter. My idle is off, it wants to stumble a bit. It doesn't die, it then catches itself then idles fine, It will stumble a bit, catch itself. It continues to do that. IDK WTF is going on. I'm a bit frustrated with this damn car.

                    You know the drill... coils, plugs, vacuum leaks, throttle bodies, fuel pump relay, ICV, TPS, and or the tune with respect to fuel trims. Enjoy S54 ownership and custom tunes

                      I don't mind the stumble, in the idle. I mean if everything looks good, I'll just start beating on the damn things NBD! I've had this car for almost 20 years, it's just a fresh rebuild.

                        clear all codes and see which ones come back. I don't think crank sensor is bad as it never will.
