Hello to all Members. I need your help. More than a month that I'm looking for the problem of turbo boost pressure on my S2. S2 has installed a turbocharger KKK26-29, Vehicles RS2, exhaust 70mm, exhaust manifolds RS2, admission RS2, green injectors, fuel pressure regulator 3.8 bar Forge 007 with red spring, and 300kPa MAP ECU chips HAMMON-MOTORS . The turbo boost pressure stays at 1bar, the car runs but having finished in 2nd and 3rd is limited to 0.3bar until I turn off the drive and reboot. The model is a 3B. The Wastegate was repaired several months ago, might be the cause of the problem? I attached a video that you may see the 100-180km / h. Thank you very much for your attention.

I do not think I've proven, but if the blow should be disconnected? disconnect the plug tonight, sorry but I'm English mechanics and a little green hehe.
He said a friend mechanic to disconnect the tube from the N75 to the Wastegate and control to whatever blows. Another thing, it is normal for the turbo starts to blow from 4800rpm ¿?Comment

if you have a low boost. they must have a leek, wasegate spring is too soft, or the blow off is week.. do some tests on blow off. I have this problem on my 3b.
if you have a low boost ...remember it is a mehanical problem - not electrical.Comment

Then the problem may be in the dock or in the spring Wastegate or Blow off? this week I have to get a spring to 2.1 barComment

Check the Bypass Valve, I had simular issue. If there is an limitation (like safe mode), there must be an additinal leek, or check the knock sensors.Comment

It could be your maf-turbo hose collapsing under the suction your turbo is producing, ive heard of this causing the 1bar max boost situation, Happened on my S2 briefly,Comment

Kilian are you using the same eproms as i have installed in my ECU and Ferni too?
because these chips was made for k24 7200..... with RS2 injectors asyou have installed yes...but this turbo must suck much more aire than k24 7200
in th video... it seems that your car dont walk nothing¡¡
check the maf electrical connection
and install your forged engine¡¡¡
