The Cobalt SS Supercharged and the Ion Red Line will get some "staged" upgrades soon; although for the average car enthusiast, a few months seems much longer than "soon" would imply. Stage 1 consists of a ECU recalibration and larger injectors, and is good for about 20 HP. Stage 2 adds another 20 HP or so via a smaller supercharger pulley and another recal. The nice thing about the pulley is that power is increased by about 10% across the entire powerband. These sort of more-power-everywhere mods make me so jealous of the forced-induction crowd.
