OM646, stage 3 mods?
anyone here familiar with the OM646.811 engine with regards to tuning? current setup is 2.5" catless downpipe and a stage 2 remap/tune.
i am still on stock internals, and gearbox for that matter. so i dont really want to go over the top.
would the next step be turbo/intercooler/injectors, or are there any other alternatives to raise the current HP by 10-20 somehow else? i.e HPFP or something down that street.
current estimate from my tuner as the car stands now is 210HP/470NM
any tips/tricks would be greatly appreciated!
