Gas mileage for tuned X1 Xdrive35i?

Ardorventura · 04-17-2021, 03:52 PM

Just installed JB4 on my car. Was wonderjng if this gas milage was normal for a X1 Xdrive35i running JB4 Map 5? Gas mileage seems low for just cruising on the highway for an hour and half. Also have a highflow downpipe and 5" intercooler installed.

With MHD stage 2+ I'm averaging anywhere between 16-20mpg... I'm trying to be more careful with the throttle while driving to see how does it impact mpg's

I have the Stage 1 plug in tune, and I typically average 24mpg, mostly highway.

Some spirited driving. I'm by no means afraid to open her up off the on ramp.

Lol I get 16.6 on 93 and 16 mpg or so on e85. That's a mix of city and 1-2 hour long highway drives

Lol I get 15 if I’m lucky… running nearly FBO on MHD stage 2+ on 93. If I’m having some fun it’s more like 11-13 xD

i guess you could remove the jb, and tunes and then just drive around in econ mode.

but why even have a car at that point
