Need a new mod

[600 cummins]

I have a Quad standard box on my truck with an AFE intake and MBRP cool duals. I am wanting to get another chip to stack but I don't know what would be a good one to go with the Quad. When I figure out waht I want I am going to order the chip and a Fass or something of that nature.
Any suggestions on a chip?

What do you have on the truck now. The MP8 by TS performance rocks

He's got a standard quad box.

MP8 is good...don't care for the Quad. You could get a liftpump for about the same $$ as a power-adder.
