Here I had air flow problems using the low torque impact (250 ft-lb (339 N-M)). It was an air hog meaning it needed more flow then my setup at the time could provide. I actually had air restrictions at the couplers and plugs. What had done without thinking was to installed el-cheapo versions that didn't even match the specs. Even when I brought a 1300 ft-lbs Air Cat impact and it would not even remove my lug nuts from my truck wheels.
I have since resolve the problem by installing hi-flow couplers and plugs and I am still using the same compressor and air lines.
And upgrading was a big plus in more then one way. I just got to be careful removing nuts and nuts as they can go flying rather quickly now if I don't just bump the trigger. Also on some bolts I need to take time for the bolts to cool between impacts so I don't snap them off due to fiction heat.
With muffler that Air Cat installed things in the shop is a lot quieter too. The compressor runs less and I am using 125 ft of 3/8 air line so I can get to most things in my parking lot without using a portable air tank. Mentioning the portable air tank my old el-cheapo impact would drain it quickly so I couldn't even get a job done but the with the new impact I can remove and install a set of three bar blades on the same tank of air. It was the best 200 usd I spent on a tool in the last few years.
So NormK and Mowerfreak you might need to upgrade your impacts and if you are like me might need to save up for it but in my opinion it is well worth the effort as your work will go smoother and quicker.
