Welcome to the club. There is lots you can do to the hdi and there is lots of guides you can find on our site. First mods to look at are a stage 1 map which requires no supporting modifications. A stage 2 requires a FMIC and a stronger clutch. Dont think about putting an after market air filter on. The standard one has been proved to be very good!
