Hey, Brian... We're going through some interim development to understand a few things better. We started with the stock UIM and 60mm throttle body and then tried a 90mm throttle body. Both ran out of air at around 5500 or so. I have bought the parts for the ITB's, but haven't started building them. What we are doing is trying a different upper intake setup with a plenum about twice the stock plenum and runners that will act to increase velocity. So, we are going to dyno the car with the stock intake and video it and then take it off while still filming and put on the new intake and plenum and dyno it again still filming. The idea is to document the changes it made. Then, depending on the results, we'll finish the ITB's and do the same video thing again going from the new in take to the ITB's and dynoing them. This way people will see the range of things they can do to get to different power levels with the NA 20b. Dave is probably going to do this in about 2 weeks. Happy to let you know when in advance.

Depending on a bunch of things, I'll decide what I want to end up with...
