Upgraded ignition system or superchip?

Why not both?

Tennisshoes all i have done to it so far is a cat back exhuast single exit with 2.5 diameter pipes but im trying to get up the horse power and torque. I can't do both because I only have the money for one or the other at the moment

I was thinking about a superpaq and just so everyone knows im working with the 5.9 360 gas.

i would also suggest going with a superpaq like Superchips.
