been throwing this code for a while and it puts me into REP. Replaced the TAC, TB, MAF, checked grounds,
was at the dealer today looking over with the tech and couldnt find anything
now the truck went into REP mode and wont come out. crawled back to the dealer at about 2mph LOL and stuck it in the back since it was after hours
Allen has sent me retune but still threw codes??? anyone have any ideas?
what have we missed?
thanks!

Do you have anymore details? year, model, engine? Have you, or anyone else edited the pcm besides Nelson Performance?Originally Posted by rpav
This is part of a post from Chris at HPTuners related to this code:
"Our competitors often see this problem when you go messing with various ETC related tables that control the operation of the ETC. The TAC runs its own tests to verify operation of the ETC. In some cases this can permanently disable your PCM, hence why we won't ever add those tables.
I don;t think the PCM holds the answer to your problem"
Anyway check out this thread:
u0107 and reduced engine power - HP Tuners Bulletin Board
Post up all the details or we will be of little use to help out.
i have an 04 silverado 2500 HD with the 6.0
Allen is the only one who has tuned my truck. Not sure if he changes those parameters they talk about in the link. I throw this code at startup sometimes but not always and sometimes at idle. I had found some grounds that werent attached well and reattached them yesterday but threw it again a couple hours ago
I dont think Allen changes these parameters at all, but I could be wrong. What has changed since the vehicle ran ok? Was it the same setup and no codes before the tune?i have an 04 silverado 2500 HD with the 6.0

Nothing changed since. Im heading to the dealer again in the morning for them to go over one more time. I know the tech so that helps me at least.
Let us know what they say.
What city are you in?
^^^updated
what was the outcome from the dealership?
dealer re-routed some positives and grounds for me and problem got better but still throw this code once a week or so while driving. for instance the other day was accelerating to get on the freeway and all of a sudden ding ding ding reduced engine power. if i turn off the truck and wait til my fans cycle off then restart i can get moving again and drive to my destination. the next time i start the vehicle half the time the engine light is gone and the second start always is gone. any suggestions
