If you want maximum performance out of the impact gun, install a high flow coupling to the compressor & HF fittings to the line/tool.

Husky High Flow Aluminum Female Quick Coupler and Plug Set-036-0138H - The Home Depot

This is done to provide MAXIMUM volume (CFM) to the tool @ rated pressure (90psi).

I've seen mechanics up the pressure regulator to remove tough fasteners, dumb move. Housing failures can remove fingers, or worse, getting your hair parted by an impact hammer!.

I was planning on setting it to 105 to account for pressure drop throughout the hose. I know hose very well, I am engineer at a company that manufactures hydraulic (and air) hose and fittings! Was actually going to get my hose, fittings, and quick-disconnects from work! The 3/8" hose is rated for 350 psi WP.

Got the axle nuts off today! Glad I made the choice to go pneumatic :))

Thanks for the advice on the impact sockets - I ordered one off of amazon with 1 day prime shipping! Should be here tomorrow. I do have a dremel and I'll probably try to hack some of the material off until the socket gets here. Even if I can get it with the breaker bar, I'm pretty excited to get an air compressor. It will make a nice addition to a house that I'm in the process of buying. In case anyone is wondering what I went with:

Husky 30 Gal. 175 psi High Performance Quiet Portable Electric Air Compressor-C303H - The Home Depot

Husky 1/2 in. 800 ft. lbs. Impact Wrench-H4480 - The Home Depot

Impact is definitely the way to go. In some cases some heat may have to be applied but using the break away letting it soak over night and the impact the next day usually gets the job done. BMW uses the "Mother of Jesus" Torque on bolts and they are always tuff to get off the first time. Try the crank bolt one (another high torqued bolt of a monster)

Glad to hear it and wise choice:thumbup:

Yeah, that 800 ft/lb gun does the trick, even on the crankshaft "Jesus" bolt.

I've expanded my air tool collection (6 new tools) after replacing the little anemic "pancake" compressor with the 5 CFM @ 90 psi Rigid unit. DIYing has gotten MUCH quicker/easier.
