fuel cut?

[8urv8]

I have a big16g, 550's, walbro 255, and s-afc and I have never experienced fuel cut. What do you guy's think? I'm not complaining just a little curious.

the safc can help delay fuel cut by lowering the amount of air the ecu sees i do believe.
w/o modifying the air signal, you should see fc around 18 or so psi in fairly cool weather 19 or so if it is hot out.

Maybe that's why. The highest I've ever had my boost is 17psi. I'm still running the stock clutch also and haven't noticed any slipping. I've had the turbo about 5 months. I don't drive it really hard either, that's prolly why. Thanks for the response.

my friend has a big16G and hits fuel cut at 17.5 in the winter and 19 in the summer (mo weather, so winter means ~20F and summer means 95+). On my 14b, I hit fc at 19-20 in 15 deg. weather.

the stock clutch shouldn't have a chance of keeping up with your engine if your drive like todor and I (his won't hold over 4k and I have an aftermarket, so mine holds)
