yes, probably, no one really knows but the guy who made it.
If he wants to sell more he should come on here and talk it up. give us the info.

But yes the TCU takes in to account alot of variables before it decides to shift anything. like clutch volume indexes,etc.. I thought it said it was only for emergencies or when the car is in limp mode from a stupid sensor. thats the only time I would use it without the TCU.

I still think that the autostick mod is cheaper and easier and the TCU is controlling shifts correctly.
