From talking to some guys on the forums...
If you buy a tuner wiether it be from tom....or fs werks, I need to be able to defeat things myself if it's egr or your rear o2 or adjusting your tire size from bigger rims and tires...Its my understanding that you have to prespecify all this when you buy the tuner and that when you get it you are not able to defeat it. Like for instance if I buy a tuner not planning on buying an off road pipe but later on down the road I want one..I'd have to send the tuner back to whomever I got it from and have them defeat it then they'd send it back right Or is it tune by mail? Or if I plan on blocking off my egr completly I'd have to send the tuner back to whoever I got it from right? I plan on getting a tuner from superchips because if I'm not to mistaken you can disable them yourself.
