Hi all, I'm slowly tweaking up the GM TBI system I've got on my Rambler six... it's running pretty well but in tweaking the maps I've got to where at more than a few points the sum of the main VE table + VE adder table is > 100.

I cannot find any general discussion on how I go about pushing the table values down so that the sum is 100 or less. Do I have to increase BPW then shrink all the numbers in the main table? Do I essentially have to start over with another guess at BPW?

Sorry to bother you guys with such a basic question but I'm a bit stumped and I really can't find anything with google. I've been using Bruce Plecan's great guide but it stops short in this area.

I'm keeping good notes, and everything goes on my website, so I'll share everything. Thanks for your help.
