My GF just gifted me a Garmin Vector * and now I'm disappointed - not with the Vector but with me. I've discovered a) I don't put out the wattage I thought and b) my form sucks - L/R balance is 57/43 ish.

Anyone have any suggestions/links for training plans to build strength in one leg?

* I swear I will never whine about cat sitting for her ever again!

Nice GF!

She sure is !!
She's a runner - sometimes trains with a tri club. We were at their end of year dinner/fundraiser and it was one of the door prizes. We saw it on the table and she didn't know what it was. I jokingly told her if I won it I would win the TdF. Later, when they drew her ticket, she was called to the stage. MC sez " what bkie do you ride?" She sez " I ride a townie for errands" ( everyone laughs) "but now my BF is going to win the TdF ! "

Make sure to torque the pedals to spec. Use a torque wrench with a crow's foot attachment. Torquing under spec will screw with the readings. You may be more powerful (or more balanced) than you think. Or maybe not.

Right. A power meter is cooler than a diamond ring. Pedals which work with any wheel and crankset better than a big one.

Vector won't work with every crankset. Some cranksets don't allow enough clearance.

Honestly, at that ratio it sounds like one of the pedals was put on incorrectly. Did you use a torque wrench when installing?

That was my thought as well. My first ride with Vector, the power balance was significantly off. (about 10% difference from my Quarq, which extrapolates two sided power).

Recalibrated, and tightened the pedal that was reading low, and got much closer to 50-50.

Don't worry too much about being 50/50. Make sure the pedals are torqued properly but if you're still not even, it's not a big deal. Very few riders are, and there are a lot of coaches that will tell you to not even try to make it even if it's within 5% or so.
