Possible faulty MAF

[blownss06]

My tuner told me that my MAF may be faulty. He said its a little off. Anyways I dont want to buy a MAF if i dont have to. I attached my last log, which is when he told me.
7221

You hit the top of the MAF scale and LTFTs are quite high.
I'm going to guess that this is FI, if so you might want to think about using a COS.
WBO2 data will help in the future as well seeing how high LTFTs are.
Add commanded AFR to your PID list.

Yes I am running a magancharger@7psi. What you said is all chinese to me somewhat. I know what LTFT. Dont know what COS is and my AFR is high right know (10.5 AFR). I am waiting on my V1 to get back to me so He can adjust. Question is, is my MAF bad. Should I change it?
Thanks

You hit the top of the scale, I don't think it's bad.
