Help with plug reading…..

Ya Sean, single plane

 

Yes mark is also running the TA single plane and he gets best results at about 11.5:1 AFR

 

I increased the pvcr in the secondary today & took it for a rip.
Wideband read 13.6 only dropped to 13.5 so I got out of it.
Pulled the sensor & tested it....... it's garbage. New should be here in the am.
Hopefully the new one works
