advice on changing pullys
if i swap a 3 inch to a 2.8 pully on my supercharger do you think i will need to change anything else on my car such as a belt tensioner or injectors or do i need a retune.
i herd it was ok to run a 2.8 with gm stage 2 retune i just want to no what other people think

dont do it... your elevation with screw you.. if you were on the coast.. might be able to pull it off...
just pick up a 2.9 from nherb.. will give you a little more pep and you should be fine... no point in being risky when your talking a few hp/tq difference

hes at about a thousand feet,
being on the coast, at "sea level" will allow more boost.
the higher up you go. the less boost you get.

your right... but this is beyong how much boost.. elevation plays a much larger role in tuning.. not talking about how much #'s..
i didnt know tuning got harder at alt.
