Cant the vinlock be unlocked untill it has been performed 6 times, then there is the $150 fee?
No, once you put a tune into a vehicle, it locks to the VIN. Then it won't unlock until you return the vehicle back to stock tune.
You can tune the first vehicle as much as you want because the SCT device has stored the VIN.
If you return the first vehicle to stock and use the SCT on another vehicle, then the SCT becomes locked to the second vehicle and uses up one of the "unlocks left". If you return the second vehicle back to stock to unlock the SCT, and goto tune the first vehicle, then the SCT uses up another "unlock".
Depending on which model SCT your using, it only has 3 or 5 "unlock". After all the "unlocks" are used up, you will have to send it into SCT to be reset with "unlocks".
