Saw you had TPIS 90 TB, what is the difference between Fast 90 TB and TPIS?
I am going to do H/C mod in a few months, I am trying to get my WS6 vert into 11 on stock intern.

The TPIS uses your stock throttle cam. You have to send them a core. They also supply you with the bolts for the IAC and TPS.
The FAST uses no stock parts and is tapered more from the end of the TB to the TB blade. You will need to reuse the stock bolts from your IAC and TPS. You will also have to shorten 2 of these bolts(IAC) as the hole is not drilled as far into the TB as the stocker.
I have used both TBs and had problems with the FAST. The TPIS works great!
As for Power increases I will know how the FAST intake does on Thursday.
I lost Power with the LS2 intake.

Besides what Brad say's there also is no provision for the fresh air hose on the pass. side valve cover on the TPIS unit so I just put a small K&N filter at the valve cover to get the fresh air in.
