Whoa Mooney, sounds like a horror story. I guess I must be the exception to the rule with BL's WUR working fine right out of the box.
My AFR's are right at 12.0 at initial full boost, then once I get to around 5000 rpm's and the solenoid opens for the boost enrichment circuit, it drops to low 11's. I figure that if I'm anywhere between 11 and 12 on boost then I'm in the safe zone....not too lean to melt holes in things and not so rich as to wash the cylinder walls.
I had him set it up with 1.0 bar boost in mind but am currently running the stock .8. If I changed her back to 1.0 I suspect my boost AFR's would raise somewhat. It seems to me that when I was running 1.0 bar the AFR's held between 11.8 - 12.2, but it's been a couple/three years since then and memories fade.
