Spark plug color
I've recently gotten my turbo build "finished" enough to start road tuning and just pulled the plugs to see how they look. I think I have an Idea of what I think I'm looking at and what they are telling me, but I wanted a few second opinions if anyone cared to chime in.
Car specs:
'99 1.8
Ms2
Garrett T25
RC550 injectors (low imp with resistors)
Plugs are BKR7E's with about 30 miles on them gapped at .025 (stock coil)
