Hey I've got about 1200 miles on my rebuilt b18c gsr forged and turboed with upgraded fuel pump and 1k injectors and I checked my spark plugs and one was kinda melted is that running lean?

 

Seems like u are running lean or might not be right plugs. Just my opinion

 

Could be your tune.

 

See those specs from the flash? Thats detonation

Too much timing

Too lean

**** gas

Or wrong heat range plug

It melted because theres too much heat in that cylinder

Look into getting the injectors cleaned
