I'm considering buying a PPE programmer. There is one on the internet that I have emailed about as it just says it's a PPE Xcelerator. I asked if it was the standard or economy model and got the same answer, it's a PPE Xcelerator. How do you tell which one it is? They look the same on the front best I can tell looking at them on the net. I plan to install a blocker plate so I need at least the standard to block egr code. He said he paid 586 for it new.
