duc3518,

- If Ive said it once ive said it a million times, Drive the new car for a few thousand miles before you decide you need more horsepower. learn where the soft spots are and where your hard earned money really needs to be invested.

To answer your question Cobb already put out an accessport for the 2015 and with their stage 1 tune ( all stock ) they are posting peak gains of 11% and maximum gains of 17% across the powerband. 11% of 265 at the crank is an extra 29 horsepower, thats great for a few hundred dollars and you will definitely feel that change. Im not sure about the power loss on the 2015 drivetrain but I remember reading somewhere that the power loss from crank to wheels on the 2013 is something like 25%. that means you really need to be looking for about 65-70 horsepower at the crank to add 50 at the wheels. Why are you looking for 50? are you trying to fit within a particular bracket on a track or is it just a number that makes you feel good?

+50 at the crank is usually abtained by installing a performance inter-cooler, downpipe, turbo-back and tune. I haven't done a ton of research on the 2015 but the turbo is already working pretty hard on the 2.0L to be in the 265 range. You may not be able to expand that much on the factory turbo but thats a conversation to have with a local tuner.

Where are you located, most of the guys here have someone reputable they can recommend.

Hope that helps

Slap an intake, exhaust, turbo, injectors and pump on that thing with a huge front mount. After that, go out and beat the piss out of it.
That sounds like it's about right for you.
