[QUOTE="Bill@HPTuners, post: 15806830, member: 160581"] DW95 are a good budget big injector. I wouldn't bother with 56's. But yes you definitely need to retune, look at it this way with 10psi of boost pressure its working against your injector pressure. I think at our fuel rail pressure those 47's act more like 60lb injectors but 60-10psi working against them is like having 50lb injectors@55psi, now if you were to add another 3lb of boost you are looking at 47lb@55psi this is why the rating systems for injectors always have an NA & a boosted side to their values because boost works AGAINST injectors.
