Seems logical, I think we have already lowered the fuel pressure but as I said, need to dig up my data files

I found another, this is our best so far
you can see on the purple afr graph that something is not right, kinda hard to read and I don t use the lambda sensors for tuning, don t really trust them...
this is still with 7 psi but lower fuel level, a lot better engine rpm graph
