The tabs will need to be machined, but only if you need to use the upper speed sensor,the one used for EDC pumps. If you don't need it simply remove the sensor and it should work. My friend has one installed in his 605 N/A W124 and it works just fine. As far as SMF vs DMF dilemma, IMO both are OK, especially if you are not going to tune the engine for more power
