Don't get me wrong, my car was miles better with the remap. It felt quicker than it was (common with turbocharged cars and even more common with remapped cars) but the flexibility it the higher gears was genuinely impressive. The repair cost over 100k in clutches, a gearbox, and driveshafts would have covered the running costs of the far nicer T5 variant though!

The manufacturer know what they're doing, they wouldn't have detuned the engine for the C1 platform and even more for the automatic gearbox unless they had very good reason. The idea of taking an autobox that has been torque limited to 250NM in 1st and then wanging 450NM+ through it and expecting clean oil to make a gnats todger of difference seems very optimistic.
