Any truth to this?

I have never seen an ISX gain anything from those systems that was any power level of 600 HP or less. The only thing it serves to do is cost you money and mask fuel system problems that you may be having.

I have tested them with it installed and without, and the MG/stroke into the cylinders does not change a bit.

For competition, perhaps they are great to add that bit of front-end flow to your truck if your stomping the fuel pedal but a truck driver that hauls freight does not do this unless your a moron with an ego trip.

That is my opinion and i'm sticking to it, no one has to agree.
