Trust me, you'll want to cut the black plastic case. It WILL cause connection issues. I tried to get away without cutting a big hole and the chip didn't work cause the plastic was pushing the chip and causing no connection. I then removed everything again, cut the plastic and everything worked great. Glad it worked out that way, as I found out the tranny had upgrades so I needed to pull the chip to get it reburned and it made that task much simpler, as I now don't need to pull the entire PCM to get to the chip.
Now if Bill would just reburn that thing and get it back to me I'd be a much happier camper!!! Bill you out there!!!
