I have a Super clean 91 'Vert with Bonez intake and low restiction cats, Racing beat cat backs with Racing beat Ignition wires. Car just passed 72k and the motor is putting out 127 hp at the rear wheels according to Fast Freddie's Dyno. How do I add more power without pulling the motor or going broke getting there? Any good suggestions? The car is in Southern California so smog is always an issue. Appreciate any help you can give me. Thanks.

 

Intake and ignition upgrades are cheap and easy, and shouldn't hurt your smog.
