Wow, this is all an interesting read.
I really like the TTi street kit. But can it be improved? Sure. The items you've stated however are NOT improvements.
Having the wastegate at the front of the manifold is a mistake, Rob Raymer "thought" he knew what he was doing, when he stole the TTi design and moved the WG. The TTI location is the best possible. By placing the WG between the passengers side and the drivers side, you have reduced the total flow through the log manifold. Think about it, it you put the WG at the front of the log, ALL of the exhaust flow has to travel down the log.
3" log is un-needed, the 2.5" flows more than enough exhaust to make the power. The other issue is clearance for your spark plugs.
The biggest improvement to be made in the street kit would be getting a Tang mount turbo to fit in that space. But I gota say, there really isn't much room in there for a nice Tang exhaust housing... Maybe if you are ready to channel the frame, you can get one in there. But no kit maker is going to sell a kit that takes that much fabrication on the customers' part...
Good-Luck, you are going to need it.

Oh, and my 650+ dyno runs were made with out Methanol.

The GMR was the stainless works/Rob Raymer/QMP kit. All of which share common flaws of Boost creep, too thin materials.
