Evo fq360 service

[Rich 360]

How is this possible? ! sent my Evo in for the 40K/4 year service and it has come back with a loss of power and slightly worse fuel consumption, although the car is going back to the garage tomorrow I would like some opinions as to what they could have done as I have little faith in their ability. It is a Mitsubishi dealer but a new one. Thanks

Difficult to say, in what way is power down? What sort of differences with the mpg?

Thanks for the response, the power loss is in the last bit of the rev range say from 6k to 7k rpm, before the car would still be pulling but now that is lost. I have been on to the Mitsubishi tech helpline and they are checking with the dealer to see if they did any ecu software updates I am also taking it to a rolling road to make sure I am not going mad...Ah the fuel, normally I get > 200 miles for 45 litres but now looks like about 160 miles.
