Sensors before and sensors after demandy?

[farbeyonddriven]

I have a 2250cm 450ST hp 1750 torq. CPL 3719? 775k. demandated by some fella my buddy knows well. My question is what sensors should still be hooked up and which not and why? I’m going to pull the file and have proper “tuners” examine the disaster. I see lots of wire harnesses tied up or taped up. Also the back pressure sensor wires cut off...sensor is now a plug doing nothing...

The engine temp runs too low IMO, 175 unless uphill fully loaded the might break 200!!

He must have shut off warning lamps and things also.

The truck was originally a TMC truck, i read that from factory.... day #1 TMC has Cummins casterate(derate) ecm to 395hp and 1550 torq. To save on wear and Tare on the motor..has anyone heard similar stories?

Truck currently gets 5.2 mpg on a great day but better than it was which was 4.3. Lol

Thanks guys
