Hi guys, I've got a 93 FD runing stock twins with a power FC, HKS down pipe, decat pipe, 5 Zigen cat back system, Custom V mount set up & a custome Y pipe!!

This is what I need help with...... I bought a Greddy Profec B boost controller (Not the specII with 3 outlets on the solonoid pack, it's the one with an in & an out on the solonoid block) but I'm having problems as it will only reduce the boost to 1.1 bar, but when I turn it off it drops to 0.98 bar!! again this is too high as I need boost to be 0.9 bar!!! How have you fitted yours to your car as I've been told I might need to disconect the second pipe from the actuator & block it off (the one that comes out of the actuator at about 3 O' clock)

Please help as this is starting to anoy me as I need to sort this out before I can finish the mapping of the ECU!!!!

Cheers
Jono
