Commanded air fuel ratio Moving I have been trying to figure out while tuning my MAF why I can’t get the A/F dialed in 100%. I recently installed a cam and have completely redone my tune. SD OL the commanded and actual are right on. I just noticed that with the MAF enabled that the Commanded A/F is moving up and down around 3 to 4 k. COT is disabled OL EQ is set to 1.0 and my EQ ratio VS RPM is set for 1.16. What other table would or can intervene with Commanded AF? 
I found the fluctuation while logging AFR VS MAF freq. Any help would be greatly appreciated

yes i posted the Config i used and the one of the log's on HPT board. The commanded at WOT is just crazy. i have started over multiple times with the WOT part of the maf table. copy and pasted the error, then the commanded changes and my previous effors are lost.
