Hi all, I have a 2013 Mazda 6 estate with the 150bhp 2.2ltr deisel engine, since owning it (2016) the engine has been fine, but these days I think it could do with some TLC. In January this year it had a oil and filter change, but I would like to know what other jobs I could do to make sure the engine is running as smoothly as it can. The things I have heard is carbon cleaning? And maybe a remap ? I would like to restore any lossed power.
Any ideas or recommendations would be great.
