A.C.E Big Throttle (FD3S)

The throttle diameter is expanded to reduce the intake resistance at high rpm and realize power-up.
With proper data settings, you can power up 10ps just by expanding the throttle.
When setting up the computer for boost-up or turbine replacement, please do it at the same time.
In the second photo, the top is the normal throttle and the bottom is the big throttle.
