The bottom end of a 6.2 is not designed for the added pressure of turbocharging.. The camshaft is not profiled for it. If the fuel pump has not been recalibrated you are starving your engine..
But since you are going for this,, you might want to air to air aftercool this intake air..
But, when yer done with all that,,, go drive something with a Cummins in it.. Power starts in the low end, and stays across the board..


Good luck

I was going to say something, but i get paid to educate people on how hp is made........so nevermind.
