I recently had my car dyno tuned and one of the issues we discovered was that the boost controller wouldnt hold consistant boost above 17.4 psi. It would oscillate between 17 and 23 psi. We tried the boost controller in auto (set to 1.4 bar) and manual(set anywhere between 43 and 48). We tried setting the gain between 5 and 25 and the limiter we set all across the range and still got the same results. I am posting a picture of the dyno graph so you can see the oscillations on the top end. We were able to smooth things out alittle but still only running 17 psi. A little info on my setup.

Any information on would be greatly appreciated. I am looking to run 21-22 Psi (1.5 Bar) Thanks
