About 2 weeks ago I had to floor my truck to keep from getting hit and truck made a funny whooshing sound. i attributed this to a busted boost gauge line which i replaced. Well if i have to floor if for som reason the whooshing[like boost pressure releasing happens] but i still have around 20 psi of boost with my chip on tow haul.Any ideas where else boost could be leaking as i have checked the boots and they are fine?

ANOTHER THING I 'VE NOTICED IS THE TRUCK USED TO GO INTO HIGH IDLE IN THE MORNINGS IF IT WAS COLD BUT SINCE ALL THIS STARTED IT DOESNT, COULD THIS BE WHERE MY LEAK IS ,
