Just have a few questions about tuning my car. Its a 2000 zx3 zetec 2.0 5spd. It has stage 2 comp cams, 65mm tb, long tube and full exhaust no cat. Can i benefeit from a sct scanner? Or should i save my money and just take my car somewhere to have it tuned? Idc about overal hp gains, just want the car to run the best it can for whats done to it. Thanks.
