Will this work with a dewalt compressor (6 gallon/165 psi) that does 2.6 scfm at 90 psi? i intend to use it for my ford mustang.

Too take for op but it will absolutely work. I am using it on a compressor with same specs. Compressor will just run a lot. So what.

Whats the psi,cfm and scfm?

Robert geronimo, Hello and thank you for your question. Maximum Torque 650 ft-lb helps to break free fasteners that are stubborn or stuck, 7500 RPM (Free Speed @90PSI) helps provide high power fastening and maximum air flow is 5.9 CFM

What is the difference between the dwmt70773 and the dwmt70773l models?

The L version contains pneumatic oil.

Will it work with 21 gal central pneumatic. Max pressure 125 psi, rated for 4.7 scfm @ 90 psi. I intend to use for removing lugs torqued @ 112 ft lbs

Should work just fine. I’ve used mine to remove bolts torqued well over 200 ft lbs on pretty much the same compressor.
