I was ordering adjustable primary weights from D&D a while ago and while doing that I saw these wastegate shims they offer for $35. I know nothing about them really except they cheat a few more lbs of boost. Anyway, I ordered em cause they were cheap and figured I'd find out more about em later. Well it's later and I'm looking for some info/opinions. Anyone know about these or have any experience running em? I have my pass button toggled on most of the time and I run 25% C111 to keep the DET light away. I have the D&D barker can and Linderman boost tubes as well. Thanks in advance for any info here.
