ECU Tuning or BBA Reman??

Car is going to a local ext week for the abs ecu to be sent off for repair, and they use both so can specify either if I like... What are people's experiences, good and bad?

Personally, heard ecu can sometimes do a bit of a dodgy sales bit once they've checked your part, but equally, after thinking they might be better, bba have a horrific trust pilot rating but not sure if that's for the UK franchise... Can't ask them as they don't answer their phone though. 😕

Heard good things about both as well, just wondering how skodaites have found them...
