again unless you are up to the point of replacing the heads/cam your just wasting money. Yes you can mail it back and have him reburn it but realize you will need to reinstall the stock chip while its gone, or park it. Also realize to properly remote tune your car he needs some basic data like AFR/temps or he is just guessing. A good tuner can probably open up a couple of hp with a stock motor but its something that you will think that you might kind of feel the difference but its mainly because your wallet is lighter and you want to think it made a difference. You would be better off preparing for a remote tune by installing some aftermarket gauges.
