PM him for details. I paid somewhere near $500 but it was well worth it as the braking performance is superior to stock rotors and pads. I can jam on the brakes if needed even when towing and never worry about fade or warping (before if towing I'd have to do a panic stop then I'd warp the rotors the first time). I have info on my upgrade and notes from Kolak in my blog post - scroll down to warped brakes.

We average 26mpg urban mileage. Towing a 1800kg caravan / trailer we get about 22mpg and if on a long run over 30mpg. This is imperial calculations.

i have gde eco tune w/ dpf delete aswell... [for over a year]

i do 0 highway driving but still ...

i was told to look into o2 sensor, but any other possibilities?

thanks
When was the last time you changed your fuel filter?

Check the air filter too, but i'm assuming you already looked at that first. Turbos dont like restrictions.

My in Town / City mileage is similar to yours with same mods. Keep in mind the EVIC over estimates so you are actually getting better in reality. Depending on tire size I see from .5L to 1L/100km difference when hand calculating. Consistently .7L/100km with my summer tires. Stock size I was seeing 1L/100 difference.

fuel filter was done in the summer
and air filter was done 2 months ago

yea im tracking what i get on a tank right now ... i used to see 550-600KMS / tank
so ill see what im at on this tank...i have moved closer to work so i go 2 weeks on a tank now which is nice but i hate how the evic says 15.3L/100km
it has NEVER been that high even before tune


wondering if i should just change o2 sensor and clean MAF sensor

easy way to check is to take a long highway drive. top off fuel before and after, do at least 60 miles or so.

if you get 23mpg + you are probably fine.

I think your fine. Lately with winter blend I'm seeing 14L/100 city driving. Short distances at low speed are not economical in the CRD.

I use Powerservice when severely cold to prevent gelling. Don't think it does anything to improve mileage however.
