I am looking at adding a lift and tires to my 02 QC 1500 but am wondering which would give me the most power a Jet performance chip or dual exhaust. Will either help out the fuel economy?

 

First off by what I have read Jet Chips are not that good. I would suggest a superchips flashpaq. They seem to be the most impressive chip type mod, and can fix your speedo after you change to bigger tires. I have dual exhaust and love the sound and the small performance gain, but it was not near as big as gain as you get with the flashpaq.

Sorry i didnt read that you had an 2002... no flashpaq available. I guess go for the exhaust

 

Just know, when you add a lift and bigger tires, you are sacrificing your MPG's for off-road capability.

 

You will not see much of a gain from exhaust. I see maybe about .5 to 1 mpg gain from my exhaust (only if I have a light foot that day). I hear it is the same for a computer programmer, maybe 1-2 mpg (yet again that is only if you keep off the gas pedal). Not to mention gas becomes more expensive because some programmers run off 91 octane.
