I'm pretty sure the "gizzmo MS-2"s FCD will not work properly with the 2jz-gte. Here's why you need a GReddy BCC:

Adjustable cam gears are quite easy to install, and there are well-known settings that produce a good result:

As long as you're using the oem maf, the oem ecu, and the oem O2 sensors, you don't need to worry about your a/f ratio...regardless of the boost level. However (again) sufficient octane to match your boost level is extremely critical.

That website's description of the MS-2's FCD functionality references a "(note 1)" that I could not find. Based on that one problem alone, I'm already somewhat suspicious of this device. Again, odds are that its FCD functionality will NOT work properly for the Mkiv Supra Turbo.
