03 Cobra And Sct Sf3

If those are the only modifications to your car (no changes to the supercharger, etc), the aftermarket handheld tuning devices such as those offered by SCT will definitely help. It won't fully realize the car's potential, but it is a good start. Of course, a custom dyno tune performed by your local tuner would be ideal, provided they know what they are doing (safe tune, etc).

The tuner will also allow you to disable the rear O2 sensor circuit (you could alternatively wire in a set of resistors to "trick" the car's computer into not triggering the check engine light for the lack of cats/proper voltage at the rear O2 sensor circuit if you want - that's how folks got by before these tuners became plentiful).

G'luck.

dang that setup has got to be loud
