It's not necessary to have a rising rate fuel regulator if you have the chip. I used the rising rate pressure regulator to add fuel as boost increased...I did not have the "chip". To be sure, Jak's solution is better for fueling and most likely adjusts for non-boost cruising. Unfortunately, Jak was not around at the time as far as I was aware. We had "Group Nine". Some plan for adding additional fuel is most definitely required...your post indicates that you know this or, at least, have a computer that was re-chipped.Your modified management system holds the injectors open longer at boost than the stock system so your air fuel ratio shows "good" numbers. Without that fueling chip modification, however, running higher than normal stock boost pressures, and the stock engine management, the AR ratios will not be good and one will see a falling off of boost after the initial "spike". Hopefully my disclaimer about this in the original post will make more sense now-I used a rising rate fuel regulator because the other options, at the time, did not include a modified fueling "chip", seemed silly(the dented fuel regulator), or appeared inefficient (using the NA fuel 3 bar regulator). As stated before in the original post, there are more accurate ways of doing this. It even appears that the "brass tube" method can also be improved upon. Very cool! I apologize for any confusion.
