Has anyone ever tuned there g37 journey before. Have full exhaust, intakes, weight reduction. I know it’s a journey 😔 but trying to make the car feel a bit more power, if so was it a big difference or would it just be a waist of time...

 

The motor is the same between the journey and sport models. A tune is best done with at least intakes and test pipes / high flow cats, as those are the biggest restrictions. But even if you are stock, some people get a tune for the throttle response and for autos, transmission shift feel and quickness.

Do you plan to do a remote tune or do you have a tuner locally?

 

Welcome to the forum. I've moved your thread to the ECU Tuning section. Go read up on the topic.

Yes, of course people have tuned their Journey. All G37 models had the same power train.
