I am getting the P0172/Po175 OBD code. I'm running the U7140 Steeda 91 Oct tune. I will reset the code, and it will be fine for two or three days. Today, when I "lit 'em up" the engine light (and codes) came back on. I've cleaned my MAF sensor already. Should a Dyno tune correct the common "running lean" / "running rich" codes?

Any suggestions?

Thanks

If you are getting lean codes, it sounds like you have the wrong tune installed.
Options>show last tune written, this should read Steeda tune.
If not, you need to install the correct tune.

Thanks
