I can't help you out on this one, but maybe try to PM JD. He's a Wiz on the Vec. Also try here:

Signon and then go to the tuning section of for GEN2.
I did a great number of VEC pieces there.

I take it your logging already? Or did you get the 12.3 from a gauge or meter?
You will need to really do some VEC logging across the full RPM range, only then does it make sense to try to tune yourself. Is it easy? Yes, with logs. Can you do it? Definately, with logs.
In any event, if yuo get stuck PM me, if I can help you further.

I'm tuned right at around 12.3 on my ROE and its perfect. Why do you think you need to richen it up?

Depends on the year. Are we talking cast pistons here? If it is cast, one would want it to be no more than 12.4 and that would be for somebody that really knows their rig. If not cast, your good to go.

In fact, what are we talking about...lbs? water/****?
