    Hi guys, looking for abit of advise, have a 2002 a3 1.9tdi 130 bhp and its been remapped by the previous owner. Are there any mods I can do to improve the power apart from a bigger turbo? Look forward to your responses

    its a PD engine, so the stock injectors are fine to >200hp without any issues.

    The stock PD130 turbo is good to about 180ish with a decent exhaust and intercooler. Any more than that and you want a bigger turbo.

    The gains with any of these will be negligible. A straight through exhaust will let the turbo spool slightly quicker but that's it. A de-cat is a complete waste of money on a TDI - a straight pipe is much cheaper and better.

    There isn't much else to do other than a remap before big turbo/IC/Injectors and subsequently you'll need a clutch (and DMF / SMF conversion)
