Does anybody have to reset the Timbo Apps on a Bi-Weekly basis? It has been happening now for 3 months. I disconnect battery for about 2 hours, then i reset the APPS and truck runs fine, then two weeks later i am having the same issue.:shrug: Any feedback would be appreciated

What is it doing? I have one and haven't touched it since install.

Thanks for the response. I am getting the occasional dead pedal above 50 mph. I did a boost leak pressure test, which the results were negative on any leaks. Fuel pressure is about 12-15 psi WOT, with no drop in fuel pressure when i get the dead pedal. I hook up a scanner and get no codes. Anybody ever have issues with calibration screws or spring of the APPS assembly?

Error codes? If you got to constantly reset the APPS I got a funny feeling your either chasing a failing VP44 or got alternator noise driving the ECM crazy. So check for error codes and then have the alternator tested.

No codes. Checked the alternator using the Haynes manual method for testing. Alternator seems to be fine. I read the thread posted from rooster (TC lock/unlock issues) and followed the video you posted. My DVM was measuring 13.97VDC and 30 VAC. It appears that the score is tied. I guess the bench test is going to determine the winner. :lol:. I will keep ya'll posted.
