Message	as well. I'm heading in the same direction with my car as you 3. If we don't really gain an tq/hp from the larger TB's and plenum port matching, then why go to the trouble? As I'm sure you're aware, the problem is no one is out there doing back-to-back dyno runs, changing 1 thing at a time. Most of the data points we have to use to base our decisions from are from regular car owners who upgrade an entire system and then get their car dyno-tuned. It doesn't make sense for an individual to do the step-through approach to determine the gains of every little upgrade. There are some vendors and people like SZ who do some of the before/after dyno runs to determine gains, but even those are applicable to only a subset of the community (most are done using upgraded turbos and/or other mods). I actually used yours and Evan Wright's results to get a feel for how much power I should be making after my upgrades earlier this year. I ended up very close to expected. I plan to upgrade my intake piping and do the SZ 3" DP's at some point, and your cars have inspired me to do that. So I applaud your efforts already. You guys are pioneering the stock turbo/engine performance following, if there is such a thing. I know I'm still excited about the amazing performance to be had on stock turbos. I love all that low-end tq/hp!
