Boost problems
I have a 225 tt with an apr tune and r1 dv. However sometimes i boost 21 psi and sometimes i cant get above 15 for some reason...... the hoses are fine, what could be the problem?

Re: climate changes, vac hoses, sensor problems,
i have reached 20 psi many times in all gears, this problem is not gear specific. i do not have a boost controller and i am not throwing any codes. i have not gotten it preasure tested, how much would that run me. A friend of mine told me it could be my n75 valve but i do know much about that subject.

if you are over 20psi in first gear on a stock turbo>>>
i would say that is abnormal.
Overboosting can be due to a bad waste gate or vacuum leak....
If you call APR, they will confirm what boost numbers should be in each gear...

no argument here, but i have hit 21 many times in first gear, second gear, any gear. and thats not the problem anyways, its that i cant hit 21 in any gear anymore. i only hit 15. does no one have thoughts on that n75 valve?
