Coranado is heavy and not supper aero...just my .02...but i heard they are built tougher then columbia or cascadia.

 

D15 can go on cascadia evolution....d16 can only go on cascadia. The evolution is a little more aero.

only reason i see why power cant go up would be driveline specs series 60 were good for 515 hp in 2009 on cascadia unless injectors are different in small hp engines

 

the motor, injectors and everything else are the same. its just ecm programming that seperates them. He could program in and extra 100 tourqe and just be stock for other trucks. The problem is they size the exachast and DPF based on what the motor is speced at. Unless he upgrades his DPF he would over load it if he ups the engine. This would cause it to fail and need tons of unscheduled maintenance. Thats the problem with dpf...the motor can handle it but the tail pipe and air intakes probably can't

 

Thats true...more torque available=longer engine life and better mpg and less dpf in your case. The main problem is the EGR increasing the amount of soot produced from cooling the peak combustion in the cylinder which causes more soot and more soot means the DPF has to work harder to burn off all the soot. If you didn't travel to california, i would just delete all the emissions junk and close that chapter.

 

should be possible to grab those gains
