He’s right. I made this mistake on mine. Factory setting was 475 with a big 13 (1850 torque). Had a 550 tune installed. EGTs ran too hot and I cooked the motor. Built the engine, bigger turbo, aftermarket exhaust manifold to drop the EGTs, switched to an 18 speed with 1850 torque, 650HP tune, custom clutch. Popped the intercooler, grenaded the transmission, and chunked the rears. Custom intercooler, big rad, RTLO22918B transmission. Digital pyrometer, axle temp gauges and transmission temp gauge.

If you want anything over 550, that transmission had better read 20918B minimum. 475-550HP, you can get away with an 1850. Besides, that 400HP setup probably has a low torque transmission and 38k axles. Grenade.

“But Six, I know a guy that ran a ______with a _____ and a ______ and he did just fine.”

I was that guy. Grenade, grenade, grenade and grenade. Ran just fine…until it grenaded. So what are you really saving? Absolutely nothing. The primary reason I bought the truck was because it had a 2WS engine, had the sleeper I wanted and set up to run in northern Canada. If you don’t any specialized plans and just want a rig that performs strong and gets decent economy, buy a truck with the factory setup for a 515 Detroit and put all your money back for maintenance.

That doesn’t really mean anything without the model number

You are correct, sir. I cooked my rears running up i68 in the big hole.

I have a 14613b and mine is turned up. But turned up DDEC2 puts out less torque than a castrated X15 no doubt!
