If you increase the valve pressure (turn in the screw), you increase the valve's resistance to opening at lower vacuum levels, meaning part throttle or at idle but you also increase the occurrence of compressor surge, which is what a BOV is there to prevent in the first place.
Anyone know how a modified GTR handles with the standard 4wd torque spiltter/ Altessa Pro? More to rear wheel or what?
And i believe HKS make an aftermarket controller.. any info on this 1st hand?
Cheers..
