I just worked off nights this AM and took a nap when I got home, UPS dropped it off after lunch. My O2 sensor was acting up so I updated the firmware on the LM2 and added a new 4.9 sensor, the new sensor required a new cable as the one for the 4.2 sensor isn't compatible. That part is done and ready but I have to pick up a nipple for the PCV hose. Then set the spacer up in the mill and drill and tap the hole. Hopefully tomorrow afternoon it'll make some noise. It's supposed to be really hot so I may wait to drive it early Sunday before it gets hot.
