Something to keep in mind. If your state is performing OBD2 checks, they could ID computer from different car/year and fail you. Mass started with identifying Europian code that was flashed into some car's ECU's and eventually they started picking out non-native ECU's. NH was late to the game, but they are starting picking them out. So before you truely commit to a 5sp ECU from a trooper, make sure your will not have this problem.
