Who did the remap Dave and what did it take it up to?I have a petrol Ghibli as a daily. Its a 2014 base with a remap to S power level and really happy with it.
Just make sure all recalls have been done (there were lots of them) on early cars. I get around 29 mpg average with enthusiastic driving.
Sounds great as well. Not V8 great but lovely nonetheless
Good luck.
