The cam and engine would pick up somewhat off of a tune, but the injectors really need to be corrected. The car would make more power and should be more streetable as well with a tune.

That's because the PCM thinks it has a smaller injector, so it's keeping it open longer than it should.

A decent mail order tuner can probably get you just about as close as a dyno tune for no more than you have done. And depending on which tuner you go with it will probably be a better overall tune with mail order. And it would be much cheaper.
