    Hi my 2.0tdi boost gauge shows 26psi boost holding under acceleration is this normal ? Read the sig for performance mods, i converted 26psi into bar and its 1.79 bar it seems high to be running that sort of boost on stock turbo ?
    Thanks

    Bit high for a standard turbo

    Mines at 2.5 bar which is around 34 psi I think, or so vagcom says it is which is putting out around 175bhp apparently.

    Also when accelerating boost builds up really fast and when i release the accelerator pedal the actuator dumps boost pressure and it sounds really loud like a dump valve, its bot leaking boost ad ive hade it checked in 4 different places in the pipe work
