Here is the plot:

My last setup was a 20G XTR that made about 100WHP less than this. It was a really fun setup, but this completely blows it away! The top end of the powerband is so much stronger. It just pulls, and pulls! Nuke has been tuning in the 27-29psi range and it's been making 560-580WHP on Virtual Dyno. It is a lot of fun!

It does spool later than the 20G XTR (obviously), but the low end powerband really isn't that bad. I think it's perfectly fine for street driven, daily use. You can't mash the pedal in a high gear, but it feels plenty peppy just getting up to speed. It hits 20psi by around 4k rpm's with the 07+ STI 4th gear. A little later in 3rd.
