Blue exhaust flame at idle?

So Iím still working on my 2.7l turbo conversion. Iím at the tuning phase, and I noticed something odd the other night.

At idle, I have a blue flame out the exhaust...

Not orange, blue. Like a jet engine or a torch or something.

According to my LC-2, my car is idling between 13.5 and 14.0.

Not the best picture, but it should give you the general idea.

The flame isnít visible in daylight or with the garage lights on. Itís very visible in the dark.

Anyone ever see this? Iím thinking my lc-2 is giving me false readings?
