OK so you are hitting full boost at 1,700rpm so it seems like you are running a bit lean from 1,700rpm to above 3,200rpm I would still think about some sort of management like a emanage, SAFC, AEM FIC so you can load a smother curve. But overll you seem to be fine. TRD knows what they are doing... and as long as you don't raise the boost, an aftermarket exhaust should not be a problem.

Yep they do. Is not difficult if you know what you are doing... If you understand the basics of engine tuning and are willing to take some risks you can do it your self. My advise, look for a local Emanage tuner. This is a very popular device, finding a tuner for it shouldn't be that difficult.
