Hello everyone,
I purchased a used 01 Duramax 3500 DRW. It has a DSP5 switch. There is a tune on it because the difference from position 1 to position 5 is night and day. I had the switch what I think is position 5, it's not marked, but the truck is an animal in that position. Well, I limped my trans on the interstate going up a hill when i hit WOT. I have no idea what tunes are on this, or for that matter what program it was tuned with. I was wondering since the tune is definitely programmed can I buy the OBD2 to RJ45 cable and use the EFI live scan and tune program? I appreciate any information you can provide. Thank you in advance.
