5. The tune has made a huge improvement to the driveability of the car. It incredibly helped the bogging on start since I baby the clutch. I can even drive the car with the AC on! I haven't really noticed a difference in mileage at all. The exhaust note is much improved from stock, but definitely pops a lot more.
My only other mod is a K&N panel filter.
