Jan 24, 2010. Over-heating issues commonly reported Vehicle-Mounted In-Line tuners that control certain parameters and install between the ECM and engine/FICM?MAF/MAP harness. PPE Xcelerator (Four models but each works with all Duramax models). Jan 17, 2014. Read the installation manual for the PPE standard on their website.I am not quite clear on. Figure the rest out.Also I have read on the DP forum about the PPE programmer having the ability to disable the EGR valve but see no option for this in the PPE manual. -PPE Xcelerator Standard stacked w/ Duramaximizer and.

Have an 06 Duramax 2500, with low miles 42000, that threw a code for egr valve. Was told by local deisel performance shop that it was probably sticking solonoid valve.

I tried looking up info on line about the egr-duramax valve, and it says that the valve is 'serviceable'. By that do they mean that it is repairable, or do you need to replace it?? Serviceable could mean you can get to it. The deisel performance shop said dont worry about the check engine light being on because the valve only works at idle, when it works anyways.But if the solonoid is stuck, you don't know if the valve is stuck open or closed. Most of the aftermarket shops advertise block off kits for the egr valves. Whats the difference of blocking off the valve, or it being stuck shut.?? Can the valve be taken apart and cleaned??Thats what i would assume is 'serviceable'.

The EGR valve is a serviceable item, but the actual solonoid for them is not. What normally happens is the valve gets clogged up with soot and sticks open. This can cause low boost conditions as well as a rough idle and funny idle noises in some cases of the valve blowing open at an idle.

The EGR valve can open at ANY time the engine is running at normal engine temps, not just at an idle. The best otpion is to block it, but you can also remove the EGR valve and clean it with engine degreaser(A friend of mine swears by oven cleaner to clean them when they are really gunked up).

Also make sure it is running the latest flash available from GM as the latest flash for them specifically adresses the EGR valve issue with them sooting up and it adds in an EGR cleaning cycle to help avoid it from happening again. I have the same truck and surprised the performance shop didnt suggest doing the EGR delete. The blocker plate is what I have now, but I also have EFI live tuning that also deletes the code. I would go that route because the egr pollutes your engine by the recycle of exhaust and causes other problems down the road.

I just ordered the complete delete kit that will replace the egr valve and clean up the engine bay as well. Your 6.6 will love you by blocking or deleting the egr. Canoscan Lide 20 Driver Windows 7 X64 there. What he said - - - I deleted my whole EGR system - - had to install an LB7 downpipe to replace the factory 3 way pipe but well worth it IMHO.

I have heard about these kits as I have a lmm motor(2008) I put a Banks chip in it.

I am afraid to mess with the motor cause you really don't get more MPG? So did it help you? You need the plate as well as tuning to disable the EGR codes.

With a blocked EGR and no tuning you will have a CEL in no time. EFI live is obviously the best option, but IMO is a total waste if your not looking for all out performance.

PPE (Pacific Performance Engineering) makes programmers that block the EGR codes as well as adding performance. I'm currently running a PPE Xcelerator on my truck with no EGR, PCV, or Cat, and zero codes. Comes with 40,90,160,and 225hp settings, although I wouldn't recommend anything over 90 on a stock tranny truck.
