Did you get a tune done at the same time?

I don't think a tune would cause a no start condition.

Could be. Only one way to find out, start spending money

I'd still put money on it being the opti.

Take your valve covers off and check to see if you have any loose rockers, and make sure you have gas in the tank. Those have been the two reasons my car wouldn't start a couple of times. Worth checking the rockers anyways, to make sure it was buttoned up good.
