Boost fade

No, that's physics.

And, Kracka - sounds to me like he lowered it one full turn, then back up two full turns, so it was only one turn above where he had it before.

Bad boost controller. My friend and I were dynoing his stock turbo'd conquest at MAP and they let us use a manualk boost contorller they had sitting around, it would do the same thing, boost up to 15 psi then fall quickly to wastegate pressure.

There is nothing wrong with his MBC, he tested another; he needs to find a happy median between where it sits now and where it becomes uncontrollable.

He tested another one that spiked and he let off and switched back. Read.

I do read, I also talked him through it on the phone.

Yes, I have a brand new TurboXS mbc, same thing happened. I'll try upping the boost in little increments.

On my Joe P., 1/8 turn = 1 psi.
