BRABUS786

hi

sorry to go round in circles about power but i am stuck for new ideas to get more power. The currect mods i have done are

Brabus Full Pulley Setup
Cats all removed and middle box ( Custom System)
DMS Tuned
K&n Filters

Current Power

Torque - 600 RWHP
BHP - 470 RWPH

BHP to Engine - 570 (Fly Wheel)
These figure are 2 weeks old.

Any ideas to get more power?????
Bigger injectors? Fuel Pressure Reg?

ideally i wanna get about 550 RWHP

Thanks
