I have been working with the injection timing in a Land Rover diesel. I've managed to improve power overall using a timing calculator from idle to around 3k rpms but it then feels like it hits a wall. I've tried advancing and retarding the timing by some degrees after the 3k rpm but haven't seen an improvement. Is there anything I might be missing to work on

Can; t directly help, other than to suggest it has a rpm limiter, but for those that might it'd help if you identified exactly which engine it is, as there were several different diesel engines used in them.

Sorry, it's a td5 engine. I don't think it's a rpm limiter because it does rev past the 3k rpm, it's just like the power drops even though it still smokes.
