GMS MAF & Lean Codes

I recently installed a GMS MAF and now Im getting lean codes on bank 1&2. (P0171&P0174). Is there a viable solution to stop the codes from setting off while using that MAF?

Yes, get a tune.

My suggestion is to pull that POS off and put it on Ebay. You're much better off with the stock MAF. There are many other places to look for power.

Exactly. I had one that caused the same exact codes and also a surging idle. Put a stock descreened MAF which eliminated the problems. I also saw zero gain for hp with it.
