I'm new to the forum and to owning a beemer, just got myself a 2003 E46 316i 1.8L with 126k miles on it.
Is it worth getting it ECR remapped? Does it actually make a noticeable difference or is it mostly just a placebo effect? With a car this old is it really worth the effort or am I likely just to wear the engine out faster?
Is there anything else that's relatively cheap and non-damaging I can do to get a little more hp out of it?
