I made the decision to buy the '04 Cobra. Now, it needsto be modified I am going to keep the mods on the light side and limited to a magnaflow exhaust, pulley(s) and a dyno-tuned Autologic switch chip.

I want to uncork the performance of the motor a bit but not go wild, and I don't want the dealer fretting over the mods when it comes to warranty time. Aside from the exhaust, the Autologic chip should be easily removable when service time comes. But on the pulleys I'm a bit up in the air. I want to keep a stock belt. What is the smallest pulley I should run? Do I only need to change the pulley only on the supercharger or do I need to change the lower pulley as well? Does anybody make smaller pulleys that look stock so the dealer won't notice the difference unless he tears the thing apart? Lastly, what kind of HP improvement can I expect out of this combo?

Many thanks!

The chip can still easily be detected at a service bay. The moment you install it (read scrub the protectant compound off the ECU service port) you can easily tell if its been tampered with.
