i hear the stock boost control solenoid is not very good. seems the gm solenoid is a good cheap upgrade. now you need a tune with this? if so will a cobb stage 1 or stage 2 work with this?
Stock BCS is good until you reach a certain boost level. I am unsure of what that level is, but I can find out if needed. For stock boost levels, stage 1 and 2 and slightly beyond, the stock BCS is fine. ~Dan
