So I went out on a limb and tried a tune from justin @ twisted tuning. So far the tunes he has sent both have a boost oscillation under load and a pulsing stft under very light throttle. His response time has been very slow and it has been over 7 days since I heard from him. Has anyone else experienced this boost oscillation? I am fbo with 15t turbos, mhd 95 v7 tune or mhd e40 tune does not do this.

I'm trying to make my own custom tune, the last one I tried had similar oscillations. Have you tried resetting MAF and Load adaptations?

So the latest revision has fixed the oscillation. I have basically all new parts. boost solenoids, injectors, vacuum lines, turbos, plus other stuff that doesnt relate to boost.
