Making the most of a 2012 CX-5 Diesel custom tune

[jonoscopy]

Hi all, looking to optimise my 2012 CX5 gt diesel. Going to get a remap + custom dyno tune as I feel that'll unlock some power+ economy,

Are there any other low cost upgrades that are worth it? Not interested in cams or bigger turbos, but from experience, is it worth upgrading pulleys, intake/ exhaust or

any other bits and bobs to optimise a tune? Cheers

What does the stock exhaust look like for your diesel? I have had good results deleting the second cat and replacing the OEM resonator with a vibrant high flow. otherwise, not much as far as restriction goes with these cars.
