I know it has probably already been discused but what is the very best T4 trim for a Supra? I want to make around 600 HP with minimal turbo lag. My understanding is the following is the best trim is this correct? what do you guys think?

COMPRESSOR WHEEL AR/.60 COLD SIDE
TURBINE HOUSING A/R / .85 HOT SIDE

I have all the mods, LEX A/F, 550's, 3 1/2 inch from turbo back (no cats), FPR, A/F mixture meter, 12 DEG timing, EXC.

If anything I would probably want higher end power because my CT 26 with B/C seems to come on strong at 3 and die out at 5 grand =( with the T4 I am also getting a big intercooler and T4 manifold. I want anywhere from 550-600 HP at the motor. I will buy the most common trim that you guys decide on!!
