So far i have had a hard time building any boost and have found a couple of things that are not right.
1. mbc was put in backwards.
2. my tial wastegate only has the small red spring in it which is no where near enough to get to 30psi. Thinking of getting the large red one to go with it.

Now here are my questions.

1. I believe my mbc is a trust? Has anyone heard of this one and also is it any good or should I get another one?
2. I noticed after removing my wastegate that if you look around where the valve seats on the fire ring you can see a very small amount of light through there. Is this normal or do I need to do something about it?
