Default definitely not the forged ones with 3 nipples (<<LOL)

Its really hard to adjust unless you get the one that has ticks. May be. Its doesn't help with smoothing out the boost either. I think the ones built with the breaking and springs might help with the boost, or a boost machine. My boost is on and off hard.

The Forge one works fine for me. They are all pretty much the same.

Default Do you run a N75?

If you're going to run a MBC in parallel with the N75, you want a ball and spring type that does NOT have a bleed hole on one side of it (most after market do, to prevent the waste gate from getting stuck open)

VAST(vastperformance.com) is the only company I know that actually makes one like this, but you can mod an off the shelf ball and spring MBC by plugging the bleed hole.

terrible, I was pulling timing. I lost significant power on the higher rpm range
