Racechip ECU Upgrade for 520D
Hi
Has anyone installed one of these Chips for Racechip? they have 2 models but basic one cost 129Euros so very cheap but gives 232PS from standard 184PS 27% increase.
Haven't got my car yet due 7th Sept F10 520d SE, but also wondered if you should let engine run in first?
looks to good to be true.
