E85/SD2& TR6

I went with the NGK UR6 plugs at .028 but will regap them to .030. What is the AFR for E85 on a sideband that's for Gas?

I would just leave them at .028 if you already gapped them there.

With a wideband that is displaying AFR for gas, you can tune using typical gas AFR's as a starting point.

If you want a recessed tip plug I use the YR5 with my TR6 gapped a 35. They are the same plug as the UR5 just a non projected tip. I'm a pump gas guy no E85 up here.

What's should the fuel pressure be set at for E85 and 120lb injectors

I'm at the standard 43psi line off and that seems to be just fine for me.
