Is there a tuner available for a 2016 besides a custom one?
 

Looking for a tuner for my 2016. Is there a hand held one or just a custom

There's no handheld worth using. Your options are ecutek or uprev. You can get an etune with either, but best results come from a custom dyno tune.

Is that something i can do myself or is it pretty difficult?

You need to contact a tuner. You'll buy the software and they'll tune the car for you. Do this after you're done with your mods to save on costs.

Ok. I thought there might be a program i can buy and do myself, but i think ill get a custom tune
