I just got my air dog 2 installed and my gauge on my h&s mini Maxx for fuel pressure is 4-5 I was told it should be 8-10 at idle and I tried to adjust it and there is no change on the gauge. What do I do bc it jumps around a little at idle.
Mods are
5 inch full exhaust/s&b cold air intake/h&s mini Maxx/full deletes and throttle valve delete

 

Honestly, I would contact AirDog and see what they have to say.

However, someone may have experienced this issue and may chime in soon.
