If your car is tuned on uprev from one shop, then you get some upgrades later on down the road. Can i take the car back to the shop and get the tune altered "retuned" for new upgrades with out having to redo the whole tune over from the very beginng? Im getting some upgrades for my car and want to get a retune, i was told by said shop that they would have to start all over again from very beginng with tune. My car runs perfect as is. Im just gettting the si upgrade from vortech and switching injectors from 600 to 750. ALso note that i am not able to take car back to uprev cause i have moved from the area. is this true that they have to retune from the very start as if i just gotten the charger and osirus for the first time?
