I would strongly recommend you leave it alone.  Kias already have had issues with their engines and if you need to take the vehicle in for a (powertrain) warranty repair in the future and they find out the ECU was remapped your warranty claim could be denied.  Even if you restore it before you go in, they can still tell it had been altered.   Don’t give them any opening to deny a claim - It’s just not worth it.

@DayWalker is on the money. I would strongly suggest leaving the ECU alone. The only reason for remapping a stock Sportage would be if you were going to up the boost from the turbo. That is not advisable on a stock Kia motor. 

Those GDI engines already have a lot of stress on them and also are known for having problems just holding together. Introducing more boost is a good way to pop the motor, and Kia will not cover a warranty engine replacement if you have tampered with the ECU, and yes....no matter what Joe Bob says on whatever forum, the extremely high end scan tools we have at the dealerships will detect any changes.

That motor is running about as much boost as it can hold. Leave it alone and get all the life out of it you can.

You can add horsepower on a turbo motor without doing a whole lot. All an OBDII device is going to do is up the boost and pray that running premium fuel will keep detonation issues to a minimum. Think of it like overclocking a computer. Yes it will make more power, but for a short amount of time before big issues start happening. It also still voids your warranty which you are going to want intact on that car as the mileage goes up and it starts to age. Their track record is not good at all.

I'm a solid core on leaving it stock. Buying tuner chips/canned tunes is normally not a good plan. I've replaced a lot of turbos and motors in my shop from people who did nothing else but chip their car. Cars these days are filled with computers and dialed in carefully at the factory for maximum safe power/boost levels. If you want to add boost, the only safe way is beefing up the motor and other parts which gets very expensive. 

It's your car and your money and not everyone has problems, let me make that clear. I can only tell you what I have seen based on my experience. You may go 100k miles with a chip, or it could blow up in 5 miles. In my experience, it is not a good idea and my recommendation would be not to do it.

I greatly appreciate both of your input and being straight forward. I know there is a tuner chip that plugs into the OBD II port that claims to increase hp by 50 with premium fuel. Is there anything you could recommend for at least 20 or so extra hp without changing a whole lot? If you recommend I just keep it stock then I respect that. So far the car has been reliable for me as is but only time will tell. Thanks again

@mod_man You seem to have quite a bit of experience with this so I will take your word for it sir. I know I didn’t buy a sports car lol I’m only 26 but are there any upgrades you could suggest even if for minor gains?
