A $350 chip (or some pump tweaking) on either of the other trucks and the 6.5 is done for. The modifications in the link would cost serveral thousand dollars. On top of that they are yanking the motor apart with under 200,000 miles on the odometer.

The mods were to just level the playing feild no cam no heads no speed parts where used just bigger injectors and more boost due to that they had to lower compression to 18:1 ford and dodge is still lower at 17.something:1 the ford and dodge still had more boost and higher fuel rate after the mods to the 6.5, My mom codes warranty at dodge they have tons of problems with those things, my dad has worked at chevrolet for 32 years but you dont want his opinion he hates all diesels. But the duramax does have problems aluminum heads are not one of them, fuel pump problems, cpu problems but the motor itself is not an issue. Like I said before my 93' 6.5 with exhaust outpulls my buddies 97 dodge cummins with a factory intercooler and more boost. And they didn't yank it apart it says there were no problems after 200,000 after mods and the truck was then sold in may 06' to an employee whom still drives it
