I ran some 0 to 20 and 0 to 60 tests and found that larger diamter piping from the turbo to the intercooler and to the throtle body helped pre boost power as well as power under boost.

I have upgraded all the piping from the turbo to the throttle body to 2". I cut more than a second off on the 0 to 60 and get better throttle response.
