Dial type torque wrench, sorry I'm dense

Torque the injectors down to 82 in lbs. You will notice a difference in how it runs. It will also save you from having a leaking injector caused by it having low preload if your top end service is prolonged. So if you set it to 82 in lbs and they loosen off a bit over time then chances are you will still be at or over the 71 in lb spec. I have had very good success with this method. I have had engines come in for service and the injector preloads were in the 50's. 2 of them were leaking as the low preload allowed combustion pressure to carbon up the pintle inside and fail the test.
