Alright I just got back from the dyno. I had to make some compromises in the comparisons you are going to see, but I don't think it messed up the results that much.
The peak I got was on the final run and it was 255.57 rwhp and 247.51 rwtq. That however was unfortunately taken in 5th gear. The other pulls were taken in 4th. Don't ask why because I couldn't tell ya. So what I did was throw out the highest baseline, which was 246.61 rwhp and 242.41 rwtq.
I compared the middle of the road Crawford pull to the middle of the road baseline and the worst baseline. For some reason, when I read the highest baseline on my reader software, the curves cut out between 4500 and 6000 rpm, or I would have compared the middle Crawford pull to the high baseline, even though that's not really fair.
Read the results for yourself. I'm very happy with it. Based on what Doug told me about dynoing the plenum (warming up the oil to the right temp), I probably could have gotten a few more hp up top, but my tuner was doing something for his racing team so we were a bit more rushed. All in all, good gains, great sound (or lack there of), and definite difference in driving experience. And mine looks like a million bucks! Pictures of the plenum on Doug's car are included, and I have pictures of the inside and whatnot but my camera is acting up.
Enjoy!

With FI the Plenum is more like a safety buffer to allow more boost or safer boost at lower levels depending on how you tune.
More room for air in, more hot exhaust out is a no brainer for me on FI. Mine was road tuned via ECU though for perfect A/F and timing and the plenum helped,
Plus stock plenum on FI is like black socks with new white Air Jordan tennis shoes
Peas!
