Thanks to the supplied AMP plugs, these chiptuning units can be easily connected and they scrupulously respect the power reserves and motor protection systems of the german manufacturer.
Fast delivery, had an initial issue with one of the connections, but 1 phone call and a technical email later all resolved., I have tried racechip previously but I am more impressed with this company.
Delivery speed is slow. More than week and nothing happens. If your process is slow you should give clear indication about that fact in confirmation. Setting expectation level is good idea.
When I ordered, there was no stock for the particular car I owned. I waited one week for the stock but had to write in to check what was the status. However, I must say the response was good.
ALL WENT WELL
I would recomend to have whats app, sometimes I need to talk online and its easir than emails
