I have read several posts on the Jet chip for the ecotec. It seems to be the only one advertised, however it apparently sucks and does nothing becuase the 2.2 ecotec can not be "chipped". I just heard about three other choices, the Hypertech, Superchip & the best Diablosport. The Diablosport is apparently an ecu reprogramer that saves the stock ecu settings, then writes on a new enhanced program that will give about a 10hp gain on a stock engine. Who has used this or knows anything about them???
