Mods for a 2017 Overland V6

Curious to know what horsepower mods people do to the Wk2 Overland with a V6? I've seen a few when I google around but wondering what people generally start with etc.

You can make mods that enhance driver's experience or style/sound, but there are no easy HP gains. You can manually shift and keep rpms up as a cheap easy improvement. Maybe 1-2 HP at peak rpms vs lower end compromises with a CAI and exhaust. I'm not sure if anyone tunes the V6 ECU for a WK2 application. Again maybe 1-2 HP unless you tune it for aviation fuel, where you may get 10-15. There is also NOx, but if you want real power you'll need to bolt on a supercharger kit.

I just got lost in thought. It was unfamiliar territory;

Thanks. I was considering a supercharger. Anyone put one on a v6? Curious to know how much of a difference it made.

Iíve done a little bit of googling around this and havenít come up with anything conclusive.

As ColdCase says, lots of mods to make things sounds better but I havenít seen much evidence of any increases in power/performance. I donít buy into air filters doing much and the risks of having your ECU remapped frighten me to death!

The superchargers Iíve looked at are for pre-2016 models only. I believe the ECU was encrypted from 2016 and there weíre some other changes to the Pentastar engine which make it a challenge. And, at $7-10k or thereabouts when itís all said and done, itís really a question of whether thatís the best use of those funds or whether theyíd be better spent on something with more horses....
