Not rude at all. I was expecting the question.
When he built his motor (109 W/ Champ alluminums and intake, 210 cam, T-66, XFI etc.) he borrowed the tool from his buddy at the machine shop. That was a few years back. He said he thinks he has one at work but has to double check. He has built a bunch of motors and Transmissions for a lot of local guys that have never had an issue. His Buick runs fantastic with the XFI and no issues.
If there $15-20 anywhere I was thinking I could just buy one and have it ready to go so that I don't waste a day not having a $20 tool. My time is very valuable these days and time wasted on not having a tool is unacceptable right now.
