I've got a HPA agreement rather than PCP but a clause in my agreement states;
You must not make any modifications to the vehicle without our prior written permission except where you are required to do so by law. The vehicle must be returned to its original specification prior to its return to us, failing which any customised parts will become our property.
Can't fault the engine, it's as owners and the reveiw's have said it is. Long ratios just don't suit me, mostly do 30mph zone driving and always being in third seems unnatural, 4th and the engine seems to labour
Have it out on Ford options and it doesn't says anything in the small print about trading in early
I have been thinking about this thread over the last few days when I drive my ecoboost 125ps, I really can't understand why you feel the engine is labouring at 30 in 4th gear. I can put the car in 5th at 37+ mph on a flat run and even then only feel a slight shake / judder.
If your referring to accelerating then I understand, as I would probably have to drop to 3rd.
