Before the exhaust and FMIC was fitted, I was dyno'ed at 360BHP 750NM.
When the DMS remap was done (before the above mods and in Stock form) The car went on the rollers with 278BHP and stayed on them until the best Map was found and that was the figures stated above. It's true, I can only guess what it is now but it will be MORE
When I had my 135i fitted with the Forge FMIC it made an extra 12BHP on the STOCK map. So I would hazzard a guess that the 335d with a remap would improve a bit more than this with the FMIC fitted AFTER a Remap
I am not planning another dyno run at present but that said curiosity may bet the better of me later this year and I may get a final map done and if I do I will of course post it on here.
I hope this is factual enough for you all and I have not stated anything that is not proven now
