I may try to borrow my wife's tool for examining childrens ears. That supposed to work too but I had these plugs laying around and thought I'd give it a shot. After the track, I decided to try a plug one step hotter but I still need to pull fuel out of the WOT zone of the VE MAP.

I use an 8x eye loupe, but I'm too cheep to start cutting my platinum plugs, I guess
Anywayz, mebby ya need to have a spare plug or two and shut 'er down at the trap and coast into the turnout area. That way the results won't be compromised.
A quick read some may find interesting:
