Im running Z4 AND TD05 at the moment and have seen some people upgrade the (from what i believe) the v1 + 2 380cc inhectors to the 440cc with phase 1 fitment kits, is this worth doing before getting my ESL and mapping, is there much to be gained?

boosted

380cc/min injectors good for 280hp @3 bar, 440 good for 340hp @ 3 bar. Up to you if you think it's worth that

If you're on a 16g yeah I'd go for the upgrade, make what you can with a capable turbo
Just don't drive it until you go for the map as the fuelling will be way out until the mapper sorts it out.
