tial 35mm question

well the other day i put my boost to channel 2 on my sbc-id (15psi) and right around 14.7 i start to hear my waste gate. i look at my boost gauge and its pulling to 14.7 and the drops to 13.8 and then back to 14.7 and then drops again. i was thinking this is the spring, i opened up the gate and come to find out that the spring is not colored so i have no idea what pressure it holds. what do you guys think this could be? thanks in advance.

I would of assumed the spring.

Does it do that on all your channels or just channel 2? If its just your second channel, you just need to tweak the settings on that channel. Setting the SBC-iD's can be a little tricky, but they are nice and work pretty well.
