i was thinking about my next upgrade being some kind of electronic boost controller (greddy, hks, whatever), and i was just wondering if you need to get it tuned to have the car run properly. I have everything installed right at the dealer, because they wont void the warranty if they install it themselves. I was just wondering would an E boost controller be something that the dealer could install or would i have to take it somewhere else? Eventually im going to get a dynoflash or some type of custom tune, but i want to wait until i make a couple of more mods. So far all i have is a k&n drop in, greddy Ti catback, apex dp, perrin cat delete, and O2 housing....thanks a lot
