Mines right on the turn so it the TU but not flyby wire it's cabled , a good old what's left in the parts binPower is pretty much the same, The twin vanos torque will come in lower. The TU is also fly by wire throttle and the Single vanos is throttle cable, that's also a good way to tell, One has a disa one has a throttle body. Personally I prefer the single vanos.
