Looking for some help. I have tried multiple settings. Boost seems to go from 14.5psi to 11.5 at 5k rpm. Just curious if anyone had luck at getting full boost through redline and at what setting? thanks

If you look at other forums like the Vortex, there are literally a boatload of threads on this matter. Basically, the K03 turbo and the K04 just simply cannot flow enough air or keep up with the engine to maintain full boost to redline. You need a larger turbo. If you crawl under your car and look at your turbo its intake side is literally about the size of a snail shell. VW is known to underpower their engines compared to their competitors for reliability reasons. To flow that much boost, look into turbos about the size of the Subaru VF-39 or bigger. So, in otherwords, there is no way you will be able to get this turbo to keep full boost all the way to redline.

And adding a bigger turbo, you really need a tune to make full use of it.
