        8-10psi (0.55-0.7bar) stock and 14.5psi (1.0bar) APR - I think that's right anyway

          stock peaks to .82 bar then drops to .55 bar or 12 & 8psi

          tested last week with a vdo boost gauge.

          - 08' Polo Gti, White - APR v2 - Milltek CatBack - RE 001's -

              Someone has mentioned in another thread that APR boost peaks or spikes up to 22psi. I remember this because I was going to buy a boost gauge that gave a reading up to 20 psi and then found out the GTI goes beyond that.
              So Kai your figures are not wrong and your car is not f***ed unless your car and the other guys car are both f***ed.

                The software for the GTI is available in a 1.0 bar configuration and 204 horsepower (152Kw) and 242 ft. lbs (328Nm) of torque
                I'd say that would be a pretty good indication of what boost the APR tune is set to (excluding spikes)...

                    Ok..This info i got off the guys at APR...Stock boost peaks at 7psi(about 0.5 BAR), and APR tuned boost peaks at 15 to 17 PSI(about 1.1 to 1.3 BAR).

                      I run a boost gauge and boost normally peaks at 1.3 bar before eventually settling at 0.9 bar. Diffferent fuel have seen peaks of 1.5 bar !

                        1.3 bar seems like pushing your luck if reliability is concerned? My stock Polo GTi peaks .91 at 3K rpm and settling down .5 - .6 onwards

                          KO3S turbo fitted to our cars can take up to 20-22 PSI (1.6 bar or there abouts). Talk to APR or GIAC or REVO if you have any real concerns. They are all very helpful.
