I have about 3k miles on my roadster and am looking to get some more power. Has anyone dropped in the SRT-6 supercharger? The company I work for sells STARTECH but their camshaft kit only gives me 30 HP for $4k. Has anyone had any luck with an ECU upgrade/Chips/Re-mapping etc.? How can I get the most bang for my buck without compromising the longevity of the motor - existing warrenty? I appreciate the help.
