HBP Idle and low end questions
Ok so as I understand it the secondary throttle opens later than the primary so in theory secondary bridgeport should remain closed as well (I'm not talking about port timing but throttle butterflies).
So why does it pull low idle vacuum and need to idle higher and also has the brap brap idle? Also why does it affect low end? Do most builders eliminate the secondary throttle?
