    Definitely worth!!

    Perfect throttle response. oem software feeling but much stronger and more linear . That should be done in factory. Only one minus - disabled shift light indicator on dashboard :(

    Great bit of kit!!

    Bought this as I already had the intercooler and induction kit, so I chose the mTune and map only option! Amazing! Can deffo tell the difference especially in high revs! I would probably recommend getting the full kit and installing all together as you probably would see a bigger difference! Cant wait for mr300 now!
