Hi All,

Just wondering what Greddy Profec B boost settings others on here are using on there cars ? (Or other boost controllers for that matter)

My setup consists of a Turbo Technics T34.55, Garrett -31 actuator, L8 ECU, Siemens 55's and MSD map to peak 32psi and hold 28psi.

At present the cars only peaking 28psi and dropping back boost as the revs increase.

Heres the current controller settings:-

Set:- 90%
Gain:- 10%
Start Boost:- 18psi

Interested to know what others think about the Greddy Profec B aswell ?
