I donno about that. The problem w/ the Ion Redline is that the ECU is so sensitive. Upgrading the Pully will only allow u to get full boost sooner. The ECU compensates when it sees more boost. I hear though that GM is coming out w/ a stage 1 and Stage 2 upgrades for the Cobalt SS and the Redline. I think there is an ECU reflash.
