This summer I'm going to have the supersix performance package installed. The two packages I am looking into gaurantee70 to 80 hp. My question is will my automatic transmition be able to withstand the new power. Is their any other things I should need to know before having someone install these parts(I'm to dumb to do it myself) and around how much would the pack install cost for a shop to do it. Is their anything else that would be needed on top of this pack. I'm looken to spend around $3000 would that do the trick if the package cost under $2000?
