Does my truck have a Programer/tuner??
I bought my truck from a dealer and I think I have some kind of a programer/tuner. Its always been faster than my buddy's stock 7.3 and has always blown alot more black smoke at WOT and also I'm seeing between 22 and 25psi of boost. From what I have read on here is that all of that added up Doesnt sound like a stock 7.3. .... Is there any way to figure out if I do have a programer/tuner??
When I bought the truck I installed a pro comp speedometer calibrater for the 35" tires I am running. Would have that erased anything that was previously installed by the previous owner? Or would it just stack on top of a programer/tuner? (Sorry, I don't know alot about how programmers/ tuners work)
Also, I want to install a DP tuner ... Do I need to worry if I do have a different tuner/ programer on the truck? Will that interfere with the DP tuner?
BTW, I have looked at the PCM for extra wires coming out of it and I haven't seen any. So I don't think it has a chip.
