Boost Gage or Apexi AVC-R

Hello ....

I am getting ready to install my GSR into my civic soon, I hope. I am putting in a rev hard turbo as well all in one shot. I wanted to know if I should get the Boost gage or go with the apexi AVC-R control? Right now the GSR is stock by next year the internals will be getting change and the boost level will go up to 11 or 12psi. I am asking this question because I dont want to spend money on a gage and find out later that i dont need it? Thanks for the advice

Might as well get both, because you arn't going to toss your AVCR right in your LOS so that you can check on it out of the corner of your eye when driving.
