I've never personally ran a throttle body that big, but I don't think its too big. You could even run a 102 if you wanted.

A big throttle body will be harder to tune and the last 20-40% of pedal movement will have little to no effect. I had a 102mm TB with about 420whp. At 73% on the TPS would net 101kPa all the way to redline.

It doesn't really hurt anything, you just lose resolution in the power modulation.

You'll be fine with the 95mm. The low TPS will help a lot with running as well.
