This set up is for a 993 tt the fuel injectors are 650cc x 6cyl. and I plan on running 1.2 bar boost. using the chart in the manual I come with 585cc required. what should the split be between the pre turbo and throttle body. The system is an HFS-5

I suggest running a 25% pre-turbo and 75% post IC, closer to the IC outlet rather than the throttle to gain extra induction cooling and better cylinder distribution.
