Default still chasing a boost leak??

where is the fhose? ive replaced all hoses and used a tbolt clamp for tb boot. still seems to leak boost in 2nd and 3rd gears. in most gears i hit 20 psi then taper down to about 16 or so. in 2nd and 3rd it hits about 17 then goes down to like 12psi and feels like its choppy. 710s are fairly new. pressure tested and cant seem to find anything. how much boost should i see with my apr stage 1 software? i have a darintake and straight pipe exhaust no mufflers or cats.

That is what is supposed to happen with the boost. If you think you have a boost leak get a pressure tester.. If you are running ko3's they can't hold more then 12-14lbs of boost up top. If you have ko4's on ko3 tuning. That is what the APR tuning is telling it to do

Or you can make one on your own

You should test your intake system about every other oil change.

If there is a leak (boost) you will find it with the pressure tester

as my original post states, ive already pressure tested and found nothing. where is the f-hose located i want to check it. i dont think i have ko4s but in higher gears i peak at 20 then hold 16 or so. only have an issue in 2nd and 3rd gears. its an autometer gauge so i know its accurate
