Been to apr in Milton Keynes today and decided its got to be done!
Just wondered what people think of them? Advantages disadvantages, mpg, warranty (because I think you can switch between maps on the cruise stalk) and yeh..
Thanks ben
I think it's amazing. Completely different car when it's in 95/98 mode.
MPG is roughly the same, negligible increases if any. I can still get low 40's on the way to work without trying too hard. Warranty, voids pretty much anything engine related and I'll find out in 2 months how detectable they are

Depends on how proactive the dealership are really, my last car was remapped and had warranty work done on it with no questions asked. Then again Arnold *****s/Ford didn't really seem to care about anything I did do it
Advantages are that it brings the engine to life, just completely transforms it. So much more midrange it's unbelievable. It hits hard in third gear at 3500 and from 2500 in 5th it pulls very very nicely to well over 120

Just pottering about town it reminds me of a diesel, very easy to drive.
Disadvantages, last week I had the car still spinning into 4th when I fancied a shot on 98mode. Traction is a major issue at this time of year, for me It's simply not enjoyable or worth while driving it in anything but stock mode. It might exacerbate misfire issues, pretty much a hit or a miss though. I got them when I remapped but have cured them now by messing around with the plugs.
Obligatory Figures Map, this was done in 95mode:
