2010 a4 2.0 help please!

[DBT]

I have a 2010 A4 Quattro with the 2.0 turbo. I bought the car last year with 56,000 miles on a completely stock. This past April I put a K&N drop in filter and a GIAC 93 stage tune on it. After that the car was clocking 0 to 60 around five seconds flat with temperatures around 50°. Then the car just seem like it wasn't running properly so I did some research about a PCV valve and all of oil consumption post came into view. So I took the car back and put the stock to an on it and took it to the dealer to perform the oil consumption test. For the year I've had the car it was consuming about 1 quart of oil every 2000 miles. The dealer put a new PCV valve in and replace the front crank seal because it was leaking pretty bad. Then they discovered that I had the new pistons and piston rings installed on this car at 11,000 miles. so they had me put 700 miles on it and come back to remeasure the oil. At this time they said it failed even though I saw no loss of oil on a display, and I had to take care of all the oil seeping areas......oil pan etc.....before they could proceed. So audi wanted to teardown the motor to see if I can find anything obvious, but i had to take care of the seeping loyal areas even know they were going to take it all apart after that! So at this point I just wanted to get my car back, so if you weeks went by and I went back to get my 93 tune back...... Once installed the car just felt very flat and hardly any different than stock. Last week I finally got to my tuner and we did some runs and log them...... The car is only making about 12 pounds of boost with the tune. So I checked all the clamps and hoses. So next I ordered a diverter valve the new piston style. So last night I replaced the diverter valve and the one on the car existing is the new piston style! So I took the car out last night and still no difference so I am at A complete lossand getting very frustrated! And this whole time there's never been a check engine light on or any codes. Does anybody have any input on what could be going on? Looking for help please!

Have the tuner verify the flash once again. Other than that check this thread http://www.audizine.com/forum/showth...lapper-(P0299) the P0299 code doesn't generate until the requested boost is around 5 psi lower than the actual boost. The first post in the thread covers how to do a visual check, no disassembly is required.

I'm going to first do a smoke test to see if there is a leak........just so stupid dealing with all this........seemed fine until the dealer did work on it! 😡😡 just want my performance back! Ugh!
