I have an 03' cavalier 2.2l. The problem is, any performance upgrade I do is limited by the ECU computer because it only lets the engine run within certain oporating peramaters and upgrading the ECU or ading a piggy back system voids the warrenty...to my knolage anyway. Does anyone know how to get around this without voiding my warrenty?

only advice there is is that you have to wait till your warrenty is up or void it all you can do? sorry bud i know of nothing you can do to get around it
