This happened a while back - only finally got around to posting this today.  There's not too many tuning options up here, and the guys that do tune prefer the V8's so Powertune made a trip up here to tune a whole bunch of import cars.
 
The three main cars that were tuned was a JZX100, R32 and a friends S13.  The S13 made a crazy 447rwkw running 36psi...it actually spun the wheels on the dyno so the Powertune guys think it could make up to 460rwkw.  Haha...don't mind the thongs and singlets in the workshop.

I'm probably going to get these guys to tune my MR2 when i'm finished building it.
