To keep the rear end in check you can always turn the gain down on your boost controller a bit. I've had to do that on days that it's rained at the track.

I was thinking of doing that....but honestly...I wanted to test out the straight line acceleration of the car at 8.5psi....it was absolutely sic.

If turning down the power isnt an option playing with the suspension settings should produce a slightly more forgiving result. Someone with suspension tuning experience should be able to recommend changes to reduce oversteer.
What settings were you running on your EDFC and Sway bars?
Perhaps the strong Tein springs combined with the strong Hotchkis sways are resulting in slightly oversteer happy combination? Did you find this before you put the twins on?

I experimented with the EDFC settings. I currently have my Hotchkis bars on medium front, and soft rear. The EFC was set at fill stiff front, and 10 rear...so the suspension was much softer in the rear. The result was a more planted rear end...but still wanted to oversteer.
I think swtiching to 255's in the front from 245's also increaed the oversteer tendancy. I will try stiffening the front bar, and leaving the rear as is.
I havent tracked my car with the TT...so I cant comment on before/after.

Those settings sound about right with the options available.
Other options might be:
To try softer springs in the rear. You would have to increase the rear sway stiffness to control the increased body roll and help turn in but the result should be more forgiving, especially around bumpier corners etc.
Aerodynamics probabally need to be considered more now you have enough power to break traction at higher speeds, have you thought about increasing the downforce over the rear?
