So my car has just rolled 120k miles. Over time I believe my MFD has been reporting slightly lower MPG (5 to 7 mpg lower). Is there any maintenance I am forgetting to do that could cause this? The car is malone stage 2 tuned since 30k with DPF delete, so it is not a DPF load issue. I am not sure if the malone tune still uses the high pressure EGR that remains. But if so, maybe it would need a cleaning? I have a VCDS cable so I will take a look at boost pressure requested vs produced to make sure everything is working well there. Any other ideas are greatly appreciated!
