Just to update on this, I removed the Boomba tap and issue with my IAT is completely resolved.
Yesterday I logged in 34c ambient temp, IAT was at 62c and increased to 68c on a pull with meth spraying. I logged again tonight with the spacer off in 36c ambient temps with meth spraying my IAT was 41c.
Unfortunately this tap is no good. The design and quality is absolutely perfect but the heat transfer and implications to the ECU readings pose major issues.
Sorry, really not trying to dump on this thread.
