I've seen others post even higher dyno results from very low mileage, bone-stock US-spec Supras...the highest I recall seeing is about 315rwhp or so.

Yeah you are right Ive seen a few 300+rwhp baselines, the cars we dynoed (276.4rwhp,282.7rwhp as well as many others)were on a dyno dynamics and in 4th gear(the 276rwhp had 120k miles, new 15w40 mobile oil, diff. oil, coolant and plugs, the 282rwhp had an old k&n drop in filter,165k miles, new fuel filter). I should of said "the average okay-conditioned un-modified tt should make anywhere near + or - xxxrwhp at 11psi" The "industry standard" uses the dyno jet that read sometimes 15% higher. We do testing on both and have seen inflated numbers. And also elevation, gas, outside/inside temp, fans, and other correction factors play a big part of the numbers game.
