I looked at truckperformance.com and could only find intakes for the 4.3l. I have a 2001 2.2, do they make intakes for those? Also, what's the real scoop on JET chips? Do they harm your engine? There is stage 1 and stage 2, in order to put stage 2 on, does stage 1 have to be there first? I'm sick of having no power, i figured these were the 2 quickest easiest cheapest ways to gain extra horsepower....is there something else?
