Also, if you already have the increased top speed limited with the M-sport package, is this left unchanged with the tune?
thanks for the help.
Don't have enough data to be sure but the 125i Auto which was used for development is not making as much power as 130i manuals which have been on our dyno.
If you already have top speed limit removed then this remains unchanged.
