That number (30-40) was in reference to a healthy GN, and at the moment I
can't remember the HP realm.  I;ve very curious as to what your research
shows...

Given that I've already programmed over 60 chips

I was at like 420 on my 747.  The WOT even with that much work in it still
needed some refining.  I don't think anyone can say what works for them will
always work best for others.  The is a guy round here that really really
like his MAF system, and while I don't get his passion for it, it works for
him.

Yep.

 I do hope

Maybe so, time will tell.  You will be amazed what fine points can add up
to.  Sometimes it's just consistancy.

Heavens yes..    Might make a timer that works off of the VSS.  RS stopwatch
$20, and 20 for misc chips can be a handy item.  I think I mentioned what I
didi in the tuning.doc..
