Well on the topic of the boost controller ... I'm not sure on the 7mgte, but the ct26 in my car (3sgte engine) is like 6psi stock boost. One of the first things I did when I began modding my car is up the boost from there to 11psi. I'm not 100% certain with the supra what safe is, but I imagine the boost can be upped to some degree. I would check out those forums, i'm sure the people there would know a lot more. But either way, a manual boost controller is like 50 bucks and it is really easy to do. Oh and definitely first thing I would do is get an aftermarket boost gauge installed. If the supra ones are anything like the ones in the all trac, it is a POS.
