Hi all, I am thoroughly enjoying my 2014 IS350 F Sport, a big improvement over the 2011 version

However, I know the car needs a tad more horsepower to keep up with the competition. When I had my 2011 IS350 F sport the only things I could find were cold air intakes and larger midpipe/exhausts. Now that I have a 2014 I am wondering if there is anything more I can do to the car to increase horsepower?

I saw this thing when I did a google search from a company called JDM performance. For 199 they send you a box that plugs into your ODB connector and "maps your driving habits". It then either increases HP or fuel economy. I called them up because I have been told these are either fake or bad for the car, and they said that I have to keep it plugged in all the time, also I would have to accelerate harder than normal all the time if I want to increase horsepower. I do not like the sound of that.

Bottom line is have any of you guys found anything other than cold air intakes and exhausts that can boost performance for my 2014 IS350 F sport? Any suggestions would be greatly appreciated.

Headers and good choice on not going with a plug n play tune as well it would probably do 0 for ur car

That tuner is what my shop teacher would call "snake oil". It would be a huge waste of money, probably crush you MPG's, and give you about 2HP if you are lucky.
