With finger stick installed will my check engine light come on if some other issue is happening with the truck? I understand I have tricked that one circuit by the install of the FS. Just making sure all the other circuits are being monitored. My tuner's display keeps popping up with code P0101 but not getting a check engine light. Check connection at mass air flow meter and gently tapped on unit. No help. Truck is performing great even though code present. Someone said running your tuner at a high level causes more air flow, thus confusing the mass air flow sensor????

Any thoughts or advice.
