First, why are you running PV's on the front and rear?? If you truely have 2 PV's then your jetting should be square, but you should never run 2 on the street.

Second, I only run 2.5 PV, no matter what the vacuum is. You'll have the extra fuel under WOT throttle, but won't be kicking in and out under normal driving, when you're close to the rated vacuum number.

What rpm's are you at, at cruise mph?? Up until 2800-3000 rpm you're on the idle circuit, so your cruise A/F can be controlled by the idle screws, and air bleeds.

You should buy the end of exhaust adaptor for the LM, then you can read 4 cylinders at a time. You'll have to fabricate and extension out of brake line, so the probe is getting a reading at least a foot into the exhaust. It's been my experience that there is to much reversion to get an accurate reading at the end of the exhaust.

It's much easier for me to just tune the carb, then try to write things down....
