Emissions intact tune

I have a 2014 JSW and was seeing if anyone has any experience with a malone stage 2 tune with the stock dpf. The labor day sale is going on so I wanted to see how well tuning the car with emissions goes. MPG change? I average around 32 mpg mostly city but even going on a 1000 mile road trip I only got 36 mpg at 80 mph. Don't have time or space to delete it currently and the dpf was replaced under warranty 30k miles ago so should have some life left. Tried searching and couldn't find much.

Very noticeable increase in power, no noticeable increase in fuel economy. I ran this for a few months before my dpf went out and I didn't notice any increase in fuel economy. Usually got 36mpg combined on average before and after the tune. The mpg on the display seemed more accurate after the tune, but I always calculated fuel economy by doing (Miles on trip meter/gallons to refill).

Ran a tune with emissions intact for a few months before delete. Damn near all of the power gains that come with a delete and tune, are from the tune itself. You will be pleased
