Hey yall I have had a question maybe yall can help me answer. I bought a Graniteli Mass Airflow Sensor and use to run before I put on my Procharger. But after I installed the Procharger man I had tuning the truck told me they were junk and my truck would probably run better with the stocker. So I took my stocker and took the screen out of it and got it tuned by another man and just left it off. That thing is alot of money to have just sitting around not being used if I put it back on do yall think it would help performance, effect my tune, or do I just need to keep my stocker without the screen, and sell my Graniteli. I thought it would help some, just like to hear some other opinions.
