I'd like to add more power.. Any suggestions???

I really agree with tuning, and gearing. It makes all the difference in the world.

It's why ford focuses always feel so damn peppy and fast... That may sound like a strange reference, but people are always impressed by the performance of little ford focuses.

I have sold 600+ cars, and two things make people think something is fast; gearing/ tune, and exhaust sound.

Sound only satisfies for a little while, but a good responding powertrain makes you happy every time even if it is just a little 4 cylinder economy car.
