i would say skip intake... your not really pumping much HP to need more in there.. i would definetly say a tune and headers... get that truck breathing and circulating properly.

Do you have to send Nelson your PCM or is their price listed as once being sent directly to you without exchange? (I'd like to keep the stocker in case I ever have a warranty issue).

we have an 04' rcsb 2wd on the showroom floor with corsa cat back and k & n fipk. it was a noticable improvement, but programming i feel would make more of an improvement.

hey zippy what is the $ on that. I just bought mine this weekend. I am thinking about just keepig the stock setup and swapping mufflers to a 1 chamber flowmaster. then headers and a tune when the money is in.
