The bad delete collection...

Send the file to Rawze, let him look it over. He does it for free to help ppl. Even if the ECM were bad you'd need to copy the program out anyway so it can be put onto the new ECM. hookliftpete posted a link to instructions for you to copy it out.

Do i just private message rawze for the file review? I've been doing teamviewer (remote access) with my laptop and tuner for programming, instead of mailing the ecm. The weird/odd part is my truck is running pretty well, boost and egt's are good, fuel economy is good, response is good, no shudder or vibrations, power is good (625hp tune), however my boost doesnt always hold at max psi whether climbing or jaking. Sometimes it drops 2 or 3lbs, but im not sure if thats "normal" or if the tune is messed up. I pull 70K to 95K trailers up and down 10% to 14% grades, and through cold temps down to -60 degrees below zero.

My suspicion was the ecm might be bad, but im honestly just guessing. I'd be down to have rawze check out the file.
