I have a 2011 e350 bluetec.
Been looking at tunes or mods,
I know there are option from diesel power and or tuning,
Any advice on what's recommended today?

Thanks

My advice is to spend more time with family and let other less knowledgeable folks loose all sorts of efficiencies\increase emissions and ruin their tuned diesel engine!!

However if you do so, make sure you never take the vehicle to an MB dealer for diagnostic work, because they will quickly learn of the condition and will not service the vehicle and\or offer any goodwill !!

2011 is most likely past its warranty period?
Unlike Fords, Mercedes build their engine for optimal performance.
"Optimal" doesn't mean the shortest time for 1/4 mile, but fine line between passing smog requirements, longevity, fuel consumption and power output.
Pushing one of the parameters farther, will affect other parameter and I can only hope you realize that?
When I need more HP, I simply buy other MB with more power.
Some members report that chipping give few more HP, but nothing really measurable , so I am skeptic about it.
I heard 350 bluetec is a beast, so wonder what is your complain?
Do you really want to turn head by cloud of smoke behind your car?
