Does anyone have a idea about waste gate springs? I have the seven pound and using the pressure for the BC, should I keep it this way or go to a heavier spring? Still learning....
I suggest keeping the one you have now as long as its working the way you want.

Are you using a boost controller? Then here's what you need to know in selecting a spring:

In the general case, you want to select the lightest spring that still allows your boost controller to hold the target boost all the way to redline.

If you have too light of a spring, the exhaust pressure at high rev/load will be able to push the wastegate flapper open on its own.

Too heavy of a spring, and you won't be able to dial the boost down if you need.

Now, you may want to go a little heavier that "the lightest you can" so that you have room to raise the boost later down the road... There is probably a range of springs that will work now and in the future.. And don't forget, you can always tension the spring down for adjustment.
