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 have a modified calibration. But a stealth tune gives you a modified tune for ECM and TCM, but with stock CVNs. The only difference is that your flash counters will show more than when it was stock. Trouble comes if you flash in the stock tune. Now you will have even more evidence of the flahses being counted.
