Driving any car with pedal to the metal all day is going to cause problems. All the remap is doing is surely putting the map onto the engine that should have been there in the first place, but not for a variety of other reasons.
Again, Nige not "cagey" about the 170bhp, just aware that a new exhaust is needed and therefore won't do a map that high unless the car is able to cope with it.
It does state within FAQS that a 10% drop in engine life may be experienced, but probably not too much concern for most of us.
