Look at my spark plugs

[93supercoupe]

Turbo m20
Bpr7 plugs
Megasquirt with wasted spark ls2 coils
.22 gap

I dont see the cor change on the electrode, and the porcelian is brown so Im thinking a couple things. The car runs decent. Its a little poppy in the low throttle, low rpms. But it rips in boost. The motor has 300k miles and a good amount of blow by.

So im thinking a couple things
Too small of a gap

Too cold of a plug

Not enough timing (stock map under boost)

Weak spark

Let me know what you guys think. Those plugs have about 2000 miles on them.

Almost looks like charring which would mean ur running lean I thought.
