Revo Stage 2 Boost Problems

[tdubz]

im having a peoblem I just got my car chipped to Revo Stage 2 and the car is running fine no codes or anything but it wont boost past 15psi and I cant seem to figure out whats wrong, the tech hooked it up to the computer and it says its requesting 21psi but it still wont go past 15

Boost leak test.
So when he hooked it up to the computer, you mean he did a log while driving, right?
'Cause if that's the case visit www.a4mods.com and look for the boost leak test write-up to find a fix

[tdubz]

it's around 20 in vaccum though so would there still be a boost leak?

[kwimberly]

what diverter valve do you have?

[tdubz]

the audi tt one

[oregonaudi]

yeah, there can still be a leak, but it could be small and take 15lbs of pressure to show up

might be your N75.

if it goes down to 10 or 11 psi and can't boost past it, but you don't hear any hissing leaks then i'm definitely saying N75 valve.

[tdubz]

yea I dont hear any leaks or anything it's weird some days the car feels sluggish and then some days it feels like it wants to go, so u think it could be the n75?

I had the same problem and the vacuum line leading to the DV had come unplugged.

ok im gonna check it out, thats the hose that comes off the top of the dv right?
