Default disconnected maf no code?

Decided to do some sd tuning tonight,so I disconnected the maf and drove around for 20 min and got no code?

Plus I reset my ve table to stock, put in a lower timing table and added all stock kr settings back just to be safe. And I swear it feels alot stronger. All the lt readings I got where all -2 and the st readings where on average -11 to -13, so I used the stft table to adjust the ve tablem special paste by -%, readings on lt and st didnt change and truck fealt weaker. WTF? Its late and Im missing something or Ive lost my mind. I did get a manifold absolute air pressure light the other day reset it and it hasnt come back, maybe Ive got a spuradic vaccume leak. Could something be wrong with the pcm or vcm? Why didnt I get a maf code?

Leave the maf plugged in. You'll notice when you unplug it that your IAT readings are dead.

Try setting your MAF fail frequency to zero.
