Just because I can't believe it hasn't been posted yet, I just wanted to say that white exhaust smoke=coolant in combustion chamber.
Also someone mentioned earlier that it was too dificult to dig and find and aftermarket tune...It isn't. We pull calibration numbers, check them to the known calibrations in the Vehicle Information System. If any of them don't match, we take a picture and send it in. Then GM puts a block on the warranty of the vehicle in question. This is mandatory on any major engine work.

Several people have reported that the LNF does not store how many times it's been calibrated, is this what you are talking about? If it DOES store this information, you would be doing a great service to the LNF community by posting more information about this. Not for people to circumvent this, just so we would think twice before flashing at all....

It isn't about how many times it has been calibrated. It's about the Calibration ID and Verification Code. In the Tech2 scan tool, when viewing module information for PCM, it lists all Calibration ID's and their corresponding Verification numbers in order of occurence. We can check these ID's and VN's to a known database on the General Motors Vehicle Information system. If they don't match those records for that particular vehicle, that is when we document them and send it in.
Now whether or not a Trifecta tune leaves a number that can be checked I have no firsthand knowledge of, so I can't say either way. I was just responding to someone saying that dealers didn't do it because it was too expensive or time consuming. It takes about five minutes.

mine was flash idk how many times and before i went back to the dealer i flashed stock
results of that were a new motor..so obviously it worked because the service guy even told me he'd have to send in a pic no matter what
