Let me give you a tip. Take it for what it's worth. Decide what you want out of your car and then decide on your mods. You'll waste a lot less money that way And also take into consideration that you'll probably want to go faster once you get to that point. I made a cupple of mistakes bcause i didnt think of that. One of them was the exhaust. I decided on a p-log and downpipe. And i alng with many other people are here for you when it comes to tuning. I've devoted a lot of my time explaining tune related things on here as wel as else where. but the'd do the same for me...and probably have in some sort of way.
