Default Time to replace my MAF?

I've been having tje issue of power loss at 2.5k rpm for a while now, along woth the car running super lean (16.1 agr at WOT). I tried cleaning it with the crc MAF cleaner, and even alcohol and a q-tip, but no luck. I've also ruled out other potential causes of the above issue. Is it time? If so, what's a good after market MAF that won't break the bank?

Thanks in advance,

Endrance

Cleaning the MAF before anything else was a good first step. I would have done that as well. But since that didn't work, these problems could also be the result of a fuel delivery issue (pump pressure or injectors), or even front O2 sensor problems.

What do the LTFTs generally look like?

if you do need a MAF check E-bay. I picked up my 90mm GM maf for $40.

I have tested the fuel pressure, and replaced the O2 sensors so I'm confident those aren't it.

You could also try leaving the maf unplugged and see if you still have the same problem.

It's not throwing any codes except for my catless y-pipe, and I've already unplugged the MAF and it seems to work smoother with it unplugged.
