Jwebb1981 Posted May 23, 2006 Share Posted May 23, 2006 Ok, had a 06 F350 with lack of pwr in last week. Blowing black smoke, make noise from turbo. Found turbo not boosting replaced turbo test drove the piss out of the truck. I notice that it shifted harder than a normal truck. 4 days later the guy comes back saying it still has a lack on pwr during accleration. Customer told me to my and the SM face that it does it every time. One code for egr. Code was not there during last visit. SM jumps me says that I should have found the problem last time it was in. Got the SM to ride with me. I left the parking lot with both back tires smoking. I turned to him and said "Yeah, this don't have enough pwr" I was talking to the paint guy who informed me that the guy has two chips on the truck. I can't find the chips so I think he may take them off before he brings me the truck. With this new knowledge I start thinking that maybe he is over boosting the system and causeing the egr to blow open. But I can't prove that he has chiped the system. Of course custom says he hasn't chiped the truck, so I was wondering if there where any tell tell signs that I should be looking for.

LR Mike Posted May 23, 2006 Share Posted May 23, 2006 HMMM - I'm not sure about the '06, but the earlier PCMs you had to scrape away part of the circuit board protective coating to install the chip. This was easy to see once you removed the plastic cover from the side of the processor. CAN processor, though, I'm not sure how they are doing it. With a power programmer, I think it would be difficult to find.. Quote Link to comment Share on other sites More sharing options...
Gerry L. Lincecum Posted May 23, 2006 Share Posted May 23, 2006 see if there is a new reflash available, if it is ,do it, sometimes that will render the chips, programmers useless because of the different cal., has worked for me. pisses the cust. off though.

Jwebb1981 Posted May 23, 2006 Author Share Posted May 23, 2006 Well I replaced the EGR for the code and that it felled the runup test. I found out what this guy was finally talking about. It does do it everytime you take off from a standstill and go WOT. I guess this guy thinks that it is supposed to take off like a muscle car. I let him know that every diesel does that and that it is normal. Quote Link to comment Share on other sites More sharing options...
