Ok I'm running between 7-8psi of boost, It fluctuates, I don't know if it's due to the pressure drop of the intercooler or the boost controller. I can't really tell the difference with boost creep and turbo lag. But at 7-8psi I'm running 95+psi of fuel pressure which HRC reccommends. However when on the highway at full boost I notice my A/F guage reads .96 to .99 when I let off the throttle. But at wot sometimes it reads from .88 to .93. I don't know what to base the a/f mixture on. At wot and full boost or when I let off the gas? This is confusing and a lot of time on 2nd gear I stutter. Sometimes car runs like bat out of hell from a start and other times it stutters on 2nd gear. And that damn hrc fpr fluctuates like mofo, I'm hating it.

When you let off the gas, you have lots of fuel but suddenly no air. You will see a rich condition briefly. O2's are measured under load a WOT.

Your air/fuel voltage readings of .88-.93V are safe values to have. The air/fuel meter or gauge doesn't necessarily have to be monitored when the engine is not under load, or WOT. For example, when you're at idle or just cruising, the air/fuel voltage will go up and down, which is what you want to see. You'll want to pay close attention to the air/fuel voltage when you're at WOT.
