#93428, "Boost drop"


          

Im going to the track this week and need to figure this out. Im at 7psi and in 1st and 2nd gear when I punch it it drop 2psi but in 3rd and 4th it holds right on 7psi. I have checked for leakes and found nothing and if it was would it drop in every gear?

If you had a leak, yes it would drop in every gear. Sometimes boost leaks are very hard to find, the easiest way to fix one is too remove your front bumper and loosen the clamps on all your piping and intercooler and then make sure the couplers are all on good and then re-tighten your clamps. lol

I have done that and it still drops in 1st and 2nd but hold in all the other gears. What else might it be?

Do you have an exhaust leak? I had one and it caused similar problems.
