The more gas I give my car the slower it goes.

If I press the gas, the boost goes all the way up but the car bogs really bad. The more gas I give it the worse it gets. Just normal driving the car will bog hard on takeoff and up to about 3-4k rpm then just take off, kinda like extreme turbo lag. For example; at its worst I was at about 3k revs the boost was at 10psi and I was doing like 15-20 mph. Ive checked for boost leaks, timing is correct, but the problem is getting worse. When the car is not fully up to operating temp it seems to run fine for a while then comes the bogging.

Ive read every thread on here about bogging and related issues and tried just about everything.

check for vacuum leaks. mine was doing the exact same thing and i had two major vacuum leaks that only leaked during boost, not at idle. they were in the vac to my BOV and the vac line to my boost gauge. i fixed the vac leaks and my car runs great now and pulls hard like it used to before the leaks sprung up. i thought my leaks were coming from my intercooler piping but i was wrong.
