K fine well try it on a duramax, see how well that works for you.
(im warning you right now it wont; the EPA emissions controls/regs are a joke compared to 'light duty' trucks like ours; they/class-8 trucks arent required to monitor DEF fluid quality very accurately and the allowable NOx parameters are way lenient)
And I'll bet that you think that no one can get 1200 horsepower out of a Duramax or Cummins pickup engine?
It CAN'T be done!!!!!!!
What you REALLY mean is that YOU don't know how to do it!!!
