Done nearly 9000 km and getting around 14 to 15 l/100km in town and 11.5 to 12.5 l/100km on open road. But speed below 125km/hr.

What Unichip are you running?

Running Dastek Unichip, but as stated only to please the lambda sensors. Was told that the engine management system on the 2010 is very well matched and not worth the effort to use full chip mapping. Had to make a number of setting changes before the engine warning light does not come on again.

I dont believe they are getting that on the 3.7 maybe the 3.6. Mine is moderately modded and me driving normal get about 12 to 13.

But I'd probably replace your o2 sensors. What are your tire pressures look like?

Yeah I will change the o2 for sure, since I have yet to do that.

Pressure 35 psi all around

Not bad. You could even go up to 38. That may help you some.
