Chicago Pneumatic CP77332 1/2-Inch Heavy Duty Impact Wrench with 2-Inch Extended Anvil Review

While looking at impact wrenches, several people told me that they would work with a small compressor and several told me that they would not.
I purchased the Chicago Pneumatic CP7733-2 impact wrench and it worked fine with my Porter Cable Job Boss Mod. C3551 Air Compressor which has a 4.5 gallon tank and is rated 4.4SCFM @ 90PSI (max pressure 150psi). I set the compressor at 90psi (recommended for the impact wrench) and was able to remove all the wheels from my truck. I did have a problem with one lug after removing the other 5 from that wheel, but found that the wheel was in a bind. Once I jacked the tire up completely off the ground, the lug came off with ease. I then changed wheels on my dad's vehicle and it worked very nicely. It seemed to have plenty of power.
A CP Rep that I spoke with said this was a good entry level impact wrench. At one of the local tire shops I was at recently, it looked like they were using the same model impact wrench. I use mine for home use however.
During testing that I did with the impact wrench and my compressor, I found that when tank pressure was full at 150PSI, the impact wrench would hammer for approx. 20 seconds or so before the air pressure would drop enough that the compressor would need to pump up. In general, I found it necessary to let the compressor pump back up after every 4 or 5 lugs that I removed. A big compressor would be nice, but for home use you just have to stop and let a smaller compressor pump up once in a while.
One concern I have is making the lugs too tight. I had the impact wrench set on #4. After each lug was on, I hit each one again real quick. I then checked the lugs with a hand wrench and was unable to tighten them any more. I may purchase a torque wrench to go with this so I don't over tighten particularly on alloy wheels. I don't think this particular wrench is powerful enough to twist a lug bolt off, but I wouldn't recommend letting the impact wrench hammer away when tightening them.
