question for posi
i have a 07 gt500. want to send my blower to you but before i do a couple questions.
1. is it worth it to buy an l and m throttle body and plenum for a crazy amount of money over having you port the stock stuff?
2. if it is worth it do i need to buy them and then send them off to you to port match everything?
3. do i need to change my tune after a port? (no big deal to go to dyno cause i was planning on doing before and efter runs with your port anyway)
thanks in advance
