Ok, I bought this car last year and it has been tuned but I didn't get the handheld, and I went to take emissions and failed because everything is coming up as "not supported", so I know I need a new tune, so my question is if I buy a SCT handheld will it save my current tune as the "stock" tune? and the tune I get with the handheld should be good to go pass emissions with and then I can load my tune back in, am I correct? I just want to make sure I won't lose my current tune and this will work before I buy the handheld. I've tried asking on the local forums but got two different answers and I emailed a tuner company that I was going to purchase the handheld through but they never wrote me back. I'm looking to buy the tuner ASAP so I can get emissions done. Thanks.
