Anyone know how to determine Mine's ECU tune?

[CMG]

I have a Mine's a want to swap in but I'm trying to figure out it's tune. It is #0164 and it has a "No. 3" sticker on it. I assume that means it's just a light tune on stock engine, no MAF or injector change or anything. Anyone know how to figure it out?

Q3) I have a Mine's VX-ROM. And the plaque shows the serial number...Can you tell me its tuning contents through this number? A3) We can not tell you its tuning specs only by this serial number. If you give us its numbers and letters on either side of VX-ROM through e-mail attached photos, we could give you some information such as its maximum boost pressure, Speed Limiter, Rev Limiter, which vehicle year is it for and so on.If you are in Japan and send us your VX-ROM, we can check it, confirm its tuning specs and send it back to you with your payment.

Yeah I figured the answer was going to be something like that, Thanks.
