Those that have tuned or programmed
My Smarty programmer has economy, tow and performance settings. My question is, do you all tow exclusively in tow mode or any of the other 2?

Whatever Shiner. Everything has got to be an argument with you .... I'm sure you're aware of the significant changes made to the 2020 Powerstroke. Steel pistons; stronger connecting rods and main bearings; stiffened block; redesigned heads to provide better cooling; new VGT turbo; new injectors; 36000 psi fuel injection system; split stream piston cooling jets; lowered compression ratio; redesigned 10r140 transmission. Is your theory that this was done to give a little short burst of power so they could maintain bragging rights for highest in class HP? I'll put my confidence in a factory Cummins or Powerstroke having sustained HP ratings before believing the guy who throws a tuner and turbo on his truck and claims he has 475 sustained rear wheel HP.
