For your research purposes, or what have you:

This is a Pitt. Pwr file pulled from a CM875, if anyone is interested in taking a look. This truck is an offroad only truck . . .

Per an ESN lookup, the truck was originally set with AG20188 (CPL  8557, 385HP/1450lb-ft, vocational market)
The PP file is AG20209 (CPL 8558, 410HP/1550lb-ft, linehaul market)
After the file was installed, PP instructed the owner to unplug the EGR valve.

Per the truck owner "the truck ran GREAT, until it didn't anymore. . ."

Included in the zip is the PP cal, the 'untouched' AG20209 cal, and the corresponding E2M file to open them. Also made a PDF of the compare report.

Enjoy!

Sad part is when guys keep going back for more and won't listen to you. I helped fix up a diesel spec delete a while back on a 2250, Turbo was wound right up along with power jacked up and wrong calibration for the engine and on top of that the filter wasn't even empty. Got so hot it cracked the manifold. Buddy said it pulled good though and was disappointed in the performance afterwards LOL.

Had one guy tell me at a truck stop once he didn't have to shift gears hauling fuel tanker around on his diesel spec tune, was great until it broke the crank, that one was Cummins shit engine according to him though. Diesel spec is lucky there isn't much recourse for their fuck ups. I wouldn't let them tune my lawnmower
