[CarlosPTR210]

I have a problem, my car is running only 5psi :1zhelp: , I don’t know why, I have a GReddy Profec B boost controller, suppose adjusted to Low 10psi and High 14psi .

What can I do:cry: ?

Check your intercooler pipes for busted or loose clamps. Check your couplers for tears in them as well. If everything there is good, then take your blow off valve off and blow through it. If you were successful at this, you need a new BOV. Does your car run any richer by all means than it nornormally would?

check the wastegate, it could be tired and worn out if it's the original one.
