How do I adjust Boost Controller

[Ronnie01]

How do I adjust the boost? So I loosen it all the way for a lil gain or do I tighten it all the way?

Please DO NOT spool the turbo if you have messed with the MBC (I'm sure you know if too much boost is ran for too long and you can kiss that engine and turbo goodbye). For one, you need to have an aftermarket boost gauge so you can have a decently accurate measure of what boost you are running, I'm sure you've heard, stock gauge doesn't get the job done. Secondly, to get the boost you want, you shouldn't even turn it one full revolution before checking to see what boost you are set at. In the installation instructions for tuning, well for mine anyways, it said you should get on the road, and turn it no more than a quarter turn to see how the levels change. This way you have an accurate idea of how much comes with each quarter turn, half turn, and full turn.
Hope this helps.
