[QUOTE="DEEZUZ, post: 1479361, member: 1508"] First off, when did the GTP38R get dubbed "PowerMax"? I always knew it as just the GTP38R...? I have installed a few of these, even on my truck, but I did one yesterday and had noticed something weird about the waste gate. I had put about 5 PSI to the gate and it started to open and by about 15 psi it was fully open... I thought this was weird, so I got on the phone with our sister shop and see what they thought and they informed me that it should start opening right at about 5.5 PSI... Ok. How does this work when its in the truck and under load? I still hooked up the red line since its a customers truck. Does the regulating valve have ultimate say in when it opens? It seems to me the damn gate would be open all the time if it start to open at 5 psi.... On my truck I just left is disconnected... [/QUOTE]
