Nice to hear you solved the problem. You should have/use EMP monitoring while setupping as that's the only way to determine when you are in the "safe" zone. In the low rev area EMP should never go over 3bar with these small core vnts. Of course you can spool that turbo faster with 3,5bar EMP, but that will hurt bearings inside the turbo badly. Everyone should understand that while vnt is making our power range wider, it can't do miracles. For miracles use two vnts staged.
And that stop screw adjustment should not be needed when you are using professional remapping. Otherwise, well...
