C15 low power

It comes on but goes away after a few seconds. It has a couple of old codes with the cruise control trick, codes 62 and 63. Low coolant and extreme coolant temp but that was have been before all the work was done on the truck. Hoping they just didnt know what they were doing and put in the wrong trim codes and reflash, wouldn't surprise me if they derated it so the clutch wouldn't slip or something, I've had that happen on a 6 speed dodge I bought once.

 

I do both

 

Well he reflashed my ecm, it was set at 475hp 1650tq, also said it wasn't the correct file. Seems to be running way better now, will know for sure when the next job starts. I appreciate all the feedback, y'all are great! I'll update after I get a load under her

 

Ya know I'm not sure, it was a cat stock 500hp 1850tq highway file. I couldn't tell you the file number odd the top of my head
