f4i PERFORMANCE PARTS

Besides exhaust, headers, filters, and suspension what are some mods that are giving you alot of performance.
I have a 01 f4i with a K&N Filter, Full Micron exhaust, Polished intake manifold, upgraded spark plugs, Is there a Fuel Injector upgrade? I would consider getting the head ported and polished has anyone done this and if so what kind of an valve angle mod have you used if any. And as far as the electronics and the computer what works good for and upgrade.

Power Commander time for you. Esp. with an exhaust and K&N on it, you'll unleash a few more ponies, throttle more smooth, and better gas mileage.
