Small loss of fuel economy

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!

I have exact same kit but EGR deleted myself. No issues for 40k. Maybe its your EGR. Ive been making about 50-60 mpg consistency.

I used to get a reliable 50mpg, but can no longer. Now it's 43 and even on long 55mph highway trips it won't get 50mpg anymore.

tires, bearings, alignment.

Is it a DSG?

BTW what highways in RI are you staying at 55MPH at for a long time? you'll get killed at those speeds. 75 or bust!

Mine did the same before I sold it back to vw. Consistent 37 overall down to 34. Thinking the thermostat needed changing. Took longer to warm up, T-stat probably stuck open thus using more fuel, engine thinking it is still cold? Didn't bother changing it, as the timing belt was due in 10k.


Malone Stage 2 tune, drove it like I stole it.
