maf voltage
its all over the place when the car is at idle or at steady state. what could it be? as you can expect the AF ratio is also a bit jumpy, which causes an issue when tuning because its hard to make an AF correction when its up and down.

Possible maf backwash depending on what your intake setup is like.
Is the car tuned specifically for your cams or is it running more of a "base" tune? |

not sure what that is. the intake setup is a svt snorkle and box attached to a JRSC BBK. I suspect the cams may have something to do with the variation
