Yea wish I had turbo money lol!!!.I know their should be a way to run a bap to one of the pumps since they have two different circuits.Just going to try hooking it up and not going through the fpm.

Kenne bell makes a bap for twin pumps.

What I would suggest to guys running the gt350 pumps,if your in weather the drops below 50 degrees and making 12 or more pounds of boost,is to.do a log and see what your lambda is at your highest rpm setting.
