id like to get it tuned asap....also depending on the price of a shift kit, id like to go ahead and get that. 10psi on this feels ABOUT like 20psi on the other, maybe pulls a little harder, and definitely alot more turbo lag. something needs to be done about the launch, cant build up hardly any boost at all. i didnt try putting my boost higher because u told me not to, so...get back to me.
