Wastegate noise on ACCELERATION only - fixed

I had a weird issue: On acceleration only, at a very specific RPM down low, the wastegates would make noise - it made the car sound broken. If i put the car on map 0 (procede in stock mode), the sound would go away completely and it would sound correct. This was 100% software related.

To fix this I edited the wastegate duty cycle table and just raised the values down in the lower load area and the sound completely went away. Problem is 100% fixed.

I know some JB4 ISO guys have been reporting the same issue... this should fix it for you too. I assume Terry will have to adjust that map for you.
