Having a few problems with my new 400.
Firstly had to have engine ecu re-mapped as revs died on pull away. Two weeks later i now have it back and whilst it is greatly improved, i cannot imagine this car doing 0-60 in 3.5. Has anyone managed it. When first is engaged there is still a distinct lack of power and it takes time to get the power up. It seems almost impossible to do a fast smooth sprint. Once the car is rolling it is fantastic, but I couldnt even imagine taking on my mums skoda as it stands.
Sound Familiar to anyone.
