Default High fuel pressure after airdog install ?????
I just got the airdog 2 100 installed. The lowest I cen get the pressure to adjust down to is only about 24psi. What's the deal? It's supposed to come set to 15-17. Think my pressure gauge might be messed up?

Thats odd only thing I could think is maybe the pump was boxed wrong and you got one set for a 12v. I personally would perfer the 24lbs tho especially if you have a tuner.

I'd keep that. Youre covered if you ever want to do serious mods.
