[Biturbos4] timining belt replaced - now lost power

Which shop did this?

Sorry for the delayed response ..

But basically, without the big bar that sits on the cams to lock them in 
place when dialing in the timing belt, you will NEVER get the timing exactly 
right on the cams and it will cost you some horsepower. This is a frequently 
made mistake with independant shops, as people unfamiliar with how the cam 
cogs "float" on the camshafts often will take the old timing belt off, and 
put the new timing belt on with the same notches and everything lined up 
roughly the same. On other engines, this is the normal method. On this 
engine, it'll result in being off about half a tooth, which is several 
degrees- for all four camshafts.

: the traction control kick in on wet road).
: is there any thing they could have done wrong.
: the engine runs smooth and no check lights are on.
