I've already coughed up £600 for the Superchip which performs very well. I'm now about to plug in some new Air intakes. Once this is done I will take it down there for a Dyno run.
I do like the ECU remaps, I thought the BMW's were a bitch to decypher hence the plug in modules. Guess someone's cracked it.
Good to hear of other mappers out there, let me know how it works out over time.
