has anyone ever used the jet chip stage one and if so how did it work for you. also the k&N air system i was thinking of chaning that over as well. i like everone else dont like the look of the stcok. if you have replaced this was it hard to do and did it make much of a improvment. im just looking at simple ways to get a little extra out of my truck. i have a 2001 5.9 4x4 sport. used for basic driving no off road.
thanks for the info.

 

I'd recommend the superchips or the K&N... jet has been said to not do much for performance.

 

Love the K&N FIPK kit on my 5.2...It really made a difference in my books...All I have for performance is the FIPK and an Aero Turbine 3030 muffler...They made a big difference with 285/75R16 tires that I have on.

 

superchips are at least $100 more than hypertech. is it worth $450?

 

This is the least expensive K&N air filtration system I've been able to find online (eBay store). Significantly cheaper than buying directly from K&N:
