    would VCDS be able to tell? No 1 son bought a 1.8T with a sports exhaust and a boost gauge - we are wondering if it has been remapped.

    It is super easy to tell, what does it boost to?

    Stock cars are slow as ****, if it feels even remotly quick it has probably been mapped.

    Stock boost is around 8-10 psi. A mapped car will run more like 14-18 psi depending on the map.

    500kPa is 5 bar or 72psi :p

    50kPa would make more sense, as thats 0.5bar or 7.2psi.
