Unless that AFR has taped out at 18:1, I'd guess it might not be reading right. Usually our cars go the other way and go rich.

And 385hp is pretty low too...

if the graph is correct then you are running way too lean, your engine is not getting enough fuel, ecu tune asap

Get an ecu tune but do a compression test first. All guys buying these cars nowadays need to do a compression test

I'm surprised it made it through the Dyno runs if it is running that lean. What does the car have on it for cooling?

You desperately need an ECU Tune with those mods.

Either get a tune or put the stock pulley back on asap. Do some research on #8 cylinder going lean. It's common and fatal.

With the pin on the graph , you are showing 10.0 AFR. So I really don't know what's going on with the line vs numbers But with the 650 injectors I can see you running super rich (10.0).
Either way, get a tune before you do anything else

I think that's an '8' which is being intercepted by the line.

You could be right.

Maybe the dyno needs a new tail sniffer.
