Alright let me know how it goes when you adjust it for 150psi. And yeah seems like most people upgrade the regulator which I might do in the future as well. As for high flow connectors, I have a video on that so go check it out if you're interested! Thanks for watching! Don't forget to like and subscribe!
I'm also considering removing the entire panel, guages, manifold and regulator and simply install a better regulator with air filter and a custom manifold. It won't look stock but there's room to get creative. I'll let you know when this project is completed.
just the basic air on off switch 2 screws to turn it down . the 140 psi is not needed for air tools . 35 to 90 psi for home use brad gun , air hammers , impacts . ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-WqIX4Or6xYo.html
Personally I unplug it since I don't use it everyday at the moment. And no, I don't always let the air out after I'm done. It's fine to leave air in the tank as long as you maintain it and regularly drain out the air and moisture.
