I know importing a jdm supra they run less boost (turned down), are majorly limited by exhaust, smaller cam intake may be true. I think this is how they limit the power, not through an actual ECU detune or anything. Like vw I know can be chipped taking off factory limiters adding power but I think importing a mk4 supra the boost is just turned down and the exhaust limits everything, as well as the small 440cc injectors compared to the usdm 550cc injectors.

You may be correct about the size of the Japanese spec oem Mkiv Supra twin turbos. However, the ceramic turbine is less rugged when it comes to handling higher boost levels.
Note that it's very easy to crank up the boost:

...just be sure you have a boost gauge, and enough octane in your fuel (i.e. add race fuel) to match the boost level.
I agree the smaller Japanese-spec downpipe also limits performance vs. the US-spec Mkiv Supra TT.
Regarding the "gentleman's agreement", who asked for it...and who did he/she ask? Did Akio Toyoda shake hands with Stephen Harper?
