probably a load of sh!t

For all we know this tuning company could be the best in the world, that's why I never make comments about other tuners works until I've tried it for myself, even then it would have to be very bad for me to pass a negative comment.
It's impossible to tell anything about any tuning company by their website, customer reviews, sales literature and even studying maps changed by a tuner until you try their files in a vehicle for yourself.
Power figures, dyno graphs etc are important but are only part of the full story.....
