Been working on this a couple hrs now. The new arp gauge works real nice with repeatability within .0005. Sometimes the gauge will not always return to dead 0. No big deal, close enough for me. I was measuring .007-.0085 stretch with 92lbft. I backed the wrench to 90lbft and still got .007 stretch range. Backed it down to 80lbft and now between .0055 and .0065 stretch. I have a torque wrench checker and wrench seems very accurate . Both wrenches measure same readings. I have an old craftsman wrench and a newer Eastwood wrench. I will record and post some numbers later.
