haha, our cars are slow, sure mate, ya looser. i raced a v8 on the weekend and easy kept up with him its a australia ss v8 holden commmodore if ya know what that is? you guys need to look up wickypedia it says 200 hp and the 2.3 150 hp for our cars. And the guy that said the most i will get for a cold air intake is 4 hp haha good one mate and thats why my car dropped allmost half a second in me 0-60 time. and with the underdrive pully you said that will do nothing thats why my brother dropped .7 on his 0-60 time good one mate. and no mate the magnum perf chip is not just a resister its a chip that wires to your oxysencor in the exhaust and your iat sencor in the throttle body and on top of that you can adjust it by about 20 diffferent settings so if that does not advance my timing and ad more fuel then i will drive my car nude for a week.
