Thread: Recommended upgrades

Like Scotty said, what you are planning to do will not increase the performance or change anything in anyway to even require a tune.
You basically have 2 routes to go.

1. Headers, pulley drop, and tune. Mod some more drop pulleys again, retune bla bla bla....
2. Turbo < this is the better option in my opinion. Even a small turbo will wipe the floor with a fully modded M90 car.
