How do i do this?

[martinoledad]

Ok I believe im going to pull the trigger on a longtube header kit once i get a for sure answer if they are available for my truck. Also im going to get a ram air hood..... Now here comes my question I know i have to have my tunes redone, how do i do this? Do i call or fill out a form online?.... I know the headers require retuning but will the ram air hood effect anything. Also how long does it take for the tunes to come back from being redone. I also need to change my 91 performance to 93 performance.

Thanks,
