I've been using a JET TBS on my GT for over a year. When I first installed it, I noticed the difference immediately. Much better throttle response and better mileage. When I installed the Ford plenum cover last month, I had to remove the TB spacer . Again, I noticed the difference immediately, but this time, it was a negative impact. Much less torque and I needed to use more throttle to get it moving in first without stalling it. My gas mileage went down by about 2-3 mpgs.

I wound up modifying the ford plenum cover so that I could re-install the jet TBS. I'm much happier now.

Any one that says the TBS spacer does not make a difference has not tried one.

I would highly recommend it!
