Just curious to see if any other superb td owners have tried the power boxes instead of remapping, I own a 13plate 170 cr superb estate 4x4 elegance and fancy trying a power box instead of a remap. If so which do you recommend? I know the remap option is poss better but don't want the hastle of having my ecu opened and unlocked and also warranty issues.

Shark STS box? Seems to get positive reviews on here.

I think your options are limited to having your ECU opened as you have latest protected ECU.
