Has anyone ever seen or heard of a mass airflow sensor delete kit? cause my truck has one, it's had it ever since I bought it. It also has a boost fooler on it. It's a 04 F-250 6.0L. I get horrible gas milage about 8-10 MPG no matter if its around town or highway, and I know 35's and a 6" lift doesn't help but I don't think it should be that bad. Now with the maf delete and the boost fooler on the map sensor, I'm guessing the computer really has no idea how much air it is getting, so I took the boost fooler off and I guess I am going to get a maf sensor, but it doesn't show a check engine light now, could they have done something like a resistor somewhere to bypass the maf sensor so there is no check engine light?? Both of my exhaust manifolds are leaking, both from where they mount to the motor, the left side also leaks from the egt probe, and the right also leaks from where the up pipe mounts to it. could all of this be causing such a horrible gas mileage??
