Calibration Verification Numbers are CVNs. When the Dealer looks at your tune file, they check to see if the stock CVNs are there. Most modified tunes change the CVN code making it easy to spot that...

You can go with tuning software that does not manipulate the original calibration verification numbers (CVNs) so the modified tunes will still appear as stock. The only issue then becomes the flash...

This is the right way to do it. You have to do a ton of data logging to get the spark tables alone right. Heck, I put more than 100 hours in perfecting the VVT cam phasing tables to have them give a...
