I did only give a moderate tug with the wrench to check them, and not really torque on it, so I guess it's possible, but the fact that the pedals felt 'un-level' from the very first few seconds on the bike makes me still think that it was an installation error.What usually happens is there not tight... you pedal, they get looser until they strip out a portion of the thread.. if they are tight they will not do this...
