I come from the Focus Mk2 RS forum, and I've seen all this before. If you chase the big numbers, you won't necessarily get a good car. I wouldn't let anyone touch my car only Mountune. Forget the figures.
The way the car drives on the road, the reliability of their upgrades, and the fact that down the line your car will be worth more and will be much easier to sell. That's what matters.
The guys at Mountune are totally professional and everything they do has to go through Ford. No other tuner has that.
I wouldn't trust Pumaspeed to change a light bulb.
