Guilly ran a 12.9 with just a boost controller. I think raising boost is still somewhat stock, seeing as how you can do it for free... you're just getting the extra potential out of the turbos that Toyota should've done anyway.
I ran a 13.60 at 105mph completely stock with my auto on street tires. That was powerbraking it to only 1800rpms though. I now use the ebrake to hold more boost and im sure I could have knocked 2 or 3 more tenths off that time by doing so.
