ok, so what you recommend then?
only the Evolve ecu tune?
99% of our customers go for Alpha-N on S62 and S54.
The price difference is really small if you take in account that you need a new set of MAFs eventually anyway.
I have often guys who just bought MAFs and still change over to Alpha-N.
Throttle response and overall drive ability is even better with the Alpha-N compared to the tune only option.
If you can justify the little extra cost for the Alpha-N,do it.
I promise,you will not regret it!
