Engine swap but not the same performance as before
Hey guys, i have a 2008 w211 e220 i changed my car engine because it totally destroyed connection rod bearing. The swapped engine is a 2007 220 cdi but it doesn’t have the same performance as before, it is very low. Do i have to program the ECU or fuel injectors? What should i do?
