Couple buddies of mine was tuning their cars on a Dyno Dynamics dyno they just acquired:
I've taken lots of vids, but it's taking forever to upload and convert. Both cars are 3000GTs, top one put down 499HP uncorrected (the correction is positive, so the real HP is higher) at wastegate pressure which is 15 psi on pump gas. Broken boost solinoid kept up from upping the boost. Bottom car put down 400HP uncorrected at 9 psi, but only gained 30HP at 15psi due to problems we didn't get a chance to solve yet. A local Subaru WRX STi put down 448HP at 18psi and E85, I don't have a mod list on that one, but the turbo is HUGE and the powerband not so much. I have a serious headache from the noise, even with ear protection, from standing next to the dyno for 3 days straight.
So, shameless plug, if your in STL and want tuned or dyno time, Premier Tuning is the new company's name, you can PM me if your interested.
