Thanks, Atomic. I appreciate the help. Now it makes sense. Alvin said the same thing and his take is that it's the intake. I'm using a Banks box w/Airaid tube and TBSS intake - there's a strange bend in it that he thinks is causing the dump. Going to replace the tubing this week w/4" aluminum to free it up and remove the MAF all together since I'm running an SD tune. Should help...I hope. Oh, this is the new printout BTW:
