Hey PMJ... were you over at HPTuners asking about this? If so I'm the one (10_SS) that mentioned reducing the opening rate... So far so good? It's a must I believe.
I was wanting to find someone with this same blower as myself to see if you notice a spike from around 95-110kpa? This would be when the bypass valve closes I assume... so imagine part throttling it then it gets to about 95kpa then suddenly bumps to 115kpa as the bypass closes I assume... this is kinda annoying since there is no way to smoothly transition...
It actually causes a problem on a road course going around corners when your on the cusp of slide...
If you dont see it them maybe I need an adjustment or something.
my LT1 Procharger never did this... silky smooth transition.
