David,
Running open vboost will make you extremely rich at the low end. You
may get by at idle by turning the mixture screws in a bunch .. but you
really need to slip DJ190s, (big hole), in the secondary pilot air jet
position, (PAJ2), behind the slide rubbers. This will lean out your
pilot mixture. Hopefully, you are still running stock 37.5 pilot fuel
jets ....... This is one of the big problems with "optional" vboost
below 4K ......... you have to tune one way or the other ... and as
soon as those guys open up it changes the ball game. Soooooooooooo ...
you may want to tune like it is going to be open all the time, (like
.. lean out your pilot mixture), and then just close the thing at idle
if it really bothers you ......
IMHO as always .....
