03. 4x4 ext cab

My buddy has an 03 z71 with an air raid & a throttle bodie spcr. We would like to know if it would be better to go with a jet type chip or a nelson tune?

A Nelson tune, for sure. All of the handhelds are crap, IMHO. No comparison.

spend the money on a dyno tune it costs the same is by far the best for tuning
you can tell them how you drive and how you want it setup to your likings, I wouldnt mess with mailorder tunes again
