Boost Problem

[91Bird305]

I have Greddy Profec B Spec II boost controller, internal wastegate (14lbs), PT6776S Turbo. I have it set to around 2.20% on the set gain but for some reason it keeps going to 22lbs (where I have it set to) and then dips back down immediately to 20lbs and holds there. Could it be a problem with my wastegate? If I increase it to 2.40% it will go to 24lbs and then dip down to 22lbs and hold. Always being 2lbs. What could be my problem?

So what your getting is a spike. If so, turn the gain down to slow the response.

And also if you set your warning low it can do this.

My suggestion, download the manual on-line from greddy.com and read it. The one that comes with the controller is terrible.

Thanks Julio. That manual they had online helped out A LOT. I will slowly lower the gain and see what happens.
