I have a vehicle I tuned about 4 years ago most likely under the MPVI1. I now upgraded to MPVI2 at some point over the last few years. It seems that when I reconnected it told me to buy credits and i re-synced the interface but it didn't seem to show I have credit for that vehicle. also someone else tuned the car in the meantime.
do items expires. kinda sucks i paid $250 or so 4 years ago to tune this car and cannot now.
