"120psi max doesn't go far."

As a lifelong air compressor user of at least 60 years, I disagree. Volume is way more important. Also air pressure build up is far from linear. At 140 PSI those last 10 lbs. take as long as the first 100.

I tend to dial mine back a bit as long as they kick in at the right pressure. Moving both settings lower doesn't help me. Unfortunately independent adjustments don't come at consumer grade.

I'd rather it stop and start more rather than droning on and on. This is especially true with very large tanks. Those settings need to be close together.
