On the second stage of the dual controller I am running at 12-13 psi
(+ or - depending on throttle position) I have backed off 3 & 3/4 turns. The last 3/4 were adjusted 1/4 turn at a time with some test drive time included between adjustments. It still spikes momentarily @ 15-16 psi, but it is momentary and I have not gotten any codes yet. After 2 1/2 turns the adjustment range (boost gain per 1/4 turn) is more evident. I am going to operate here for a while and see if i get any codes. If so I will back off 1/4 turn at a time and test each adjustment thoroughly before continuing. The feeling I get is that now I am at the ragged edge of the compramise between performance increase and code generation by the ECU. The EGT gauge does run higher at higher boost, but it seems to me to still remain in the safe operating range. The performance is excellent. The turbo seems to recover better on transition from Boost to Vac and back to Boost again since I installed the HKS SSBOV yesterday, but that is just a first impression. More testing needed, but the BOV seems to be a good investment if you are going to run boost that is higher than stock. Since installing the TurboXs boost controller, even at a completely stock setting (adjustment Screw Completely in - clockwise) the turbo spool up time is quicker
even if the boost is not any higher. This makes it worth my investment for that reason if for no other.
