help with maf id since i purchased my car i have noticed unusually poor gas milage. it gets about 15 mpg highway and way worse around town. car has no cel light or codes stored. i noticed when cleaning the air filter that the maf does not appear to be stock. i am guessing the po installed it and did not tune it. car has headers, borla, and a g2 lid. i can hear a pop from the tailpipes while shifting between wot blasts so i am hoping my gas milage issue may be caused by a rich condition thats not enough to flash the cel light caused by different readings from the aftermarket maf. does anyone know what maf this is? im hoping maybe someone has the same one installed on their car. any info would be great, thank you.
It's been descreened for sure, and possibly ported. That will definitely disrupt airflow.
I'd personally ditch it and get a stock one on there. After a lengthy conversation with arguably one of the best LSX tuners on the planet, there's no way in hell I'd run a MAF without a screen. **Personal Opinion**

It's a strong possibility. You're saying you're not getting any CEL's... But I still wonder about the simple "tune up" things that affect mileage.
Plugs, wires, dirty MAF (or descreened and ported in your case) O2 sensors, air & fuel filters...
