Is this the ONLY way they can tell the car is tuned? I have been reading up on this whole situation lately and finding out that a lot of car guys are having the same problems but the way commiefornia is finding out is different. From what I understand the state computer checks the CVN number. Do these cars transmit this number to the state computer or is that for 05 and up?
From what I know from my smog guy it has to do with the monitors. He does it a lot for imported cars here. There can be a CA legal version of your tune made but I doubt anyone goes to that trouble now.
