would it be possable to take your ecu and ask an aftermarket ecu tuning shop to wipe the ecu and load their tuned si vertion software or even have them load a standard si software?

that way it would think its an SI rather than an I.

seems like getting the header, muffler and three stage airbox would be simple enufe just would need to get the ecu tuned, not to bad if it really gave an aditional 40+ hp
