what is better superchip or hypertec
Exhaust system to compliment the CAI. Maybe look into a Diablo Sport Predator tuner? The Predator supports '01's so you should see some improvement with it!
definitely cold air intake. One thing i did was port and polish my throttle body. gave me a little bit more power
Some headers and a K&N cold air intake system will give you a good bang for the buck!
