Guys take their chips off all the time. I have never heard of no start or any kind of issue from it. I'm not saying I disbelive you, but this is just the first I've heard of it. Doesn't the chip just overide the PCM for like incresed HPOP psi, fuel delivery, etc. And if you take an overide off anything it should go back to factory settings...if done properly.
I have been having issues with "no start" and even shutting off going down the road. One of ya'll told me CPS sensor. I went to a diesel shop the other day to had him check it out because the CPS on my truck right now is the replaced one from the recall almost a year ago. The guy was a DA. He asked my why I thought it was the cps, and I told him I talked to some diesel techs online. He said most of ya'll have probablly never even held a wrench. Asked me what kind of chip I have, I told him TS...he's never heard of it. And according to him Tony Wildman is a nobody because he's been working on powerstrokes for nine years and never heard of him. He is a GMC fan, and stated that the only one truck in his shop is a chevy and the rest have the blue oval. I was quick to point out that there are more psd on the road than duramax and cummins combined so it would make more since that there would be more powerstrokes in his shop. Needless to say I'm not going back there again.
I didn't say you WOULD, I said you COULD have starting issues with a chip left in performance mode and then unhooked..
always revert it back to stock before removing your chip, another reason to
KEEP THE STOCK TUNE.
and (you didn't but still..) don't go lumping the 6.5 in with the Duramax..
that was one hell of an engine
