Unless people want to organise it themselves or have better ideas perhaps keep the crap talk to a minimum in this thread? We always lose all the detail amongst so much crap in this section.
Honestly, who gives a f**k who likes what ECU or what the workshops in question recommend. It's a 5 minute run on the rollers so that you and others can see what your car is doing.
As a workshop I don't even use ESP but they're good guys, it's always a good day and they do whatever they can to accommodate us and even donate prizes usually.
