Anybody know if i can use a stage 2 chip from Jet?They say I must have a free flowing exhaust.I only have the cat back.Stock exhaust manifolds and cat with cat back.Should I just use the stage 1 and will i see any advantage?Many thanks.

 

For the price, you would probably get better results with a custom chip from someone like PCMofNC. Take the time to look at their tuning questionnaire, to see how the chip is customized to your specific application and mods.
