A .96 A/R T4-frame GT4276R on a 2.0L motor and you're looking at full boost in the 7000 RPM range. With a 2.4L motor the shop car AMS built was seeing full boost by 6000-6500. A far cry from 4500.

when you looked at the dyno graph (sorry it was in a mag!
) the torque just flattend straight out after 6K so it was the motors own work that got it there! as for the shift speeeds of the F1 guys, i think they still have the crown for that! but the WRC gusy are very close behind!

Also my dsm software has both antilag and two step launch. The antilag does let you build sick boost on the line. They should have this feature in hp tuners and other programs but dont' think they do.Also should be able to do a two step in software.My dsm program also has no lift to shift but requires a clutch wire mod. This all gets you off the line with big boost, the 2.4 and flywheel let the turbo spin up quick and the ball bearing design and the no lift to shift keeps you spooled up nicely.
Being able to rev the car a bit higher might also help you stay spooled up depending on your engine and combo.
No Lift To shift find a program that allows you to run that when shifting, 2 step it and setup Anti Lag for the launch.
My freind Makes 25PSI on his 2.0 GT35 GSX ON HIS LAUNCH!!!!!!!!
Befor the car moves it has that much boost, its Non ball bearing ill add
But this should be only used for drag racing
And Since you such a "Sissy" and wont power shift, ANTI LAG Is only ok for drag racing other wise it will kill your turbo faster.
