Scanmaster O2 WOT readings

[MRP78]

I have a completely stock car except for a 237 regulator and a turbo tweak chip. I've done a couple of WOT runs and get O2 readings in the low 700s (714) but no knock retard. Is this ok?

You're probably OK. Take a look at what mine looks like running fairly rich.

Richen it up 6% and see how it feels and how the O2 sensor responds.
