why aem is comming 
Yeah i visited the site and was pretty impressed. The unichip has just arrived on Malaysian shores. Introductory offer of usd460 with complete dyno tuning sounds like a steal. I'm tempted.PhD said:I'm running it in my WRX... for $700 I got a piggyback harness from TurboXS that the stock ECU sits on. Plug n' play, easy to install & remove without a trace. The map I got added 60 awhp to take more advantage of the exhaust & underdrive pulley, and actually improved overall gas mileage. Throttle response is also much smoother now compared to when I was running with just a SBC-iD for boost control. I may not be optimally tuned for all my mods since it's a generic map, but I'm pretty happy with the power gain for just $700.
This porsche racing site has a good overview of the unichip
