Im looking to put a tuner/ programmer on my 2013 Grand Sport. There are so many of them out there. Can anyone give me some advice on the biggest gains and safest tuners on the market?

I'd get a dyno tune if possible.
I really don't know much about handhelds......sorry

a professional tuner can probably get a little more out of it. than a handheld.. I bought a DiabloSport Predator for my C5 ,years ago.. it did improve performance, I have no dyno proof , but, stop watch showed better 0-60 . and 28 MPG hiway.

I agree. I use HPTuners software, but you need to learn how to use it, rather than just connect and push a button.

Are you doing any other mods?
