Hey guys i just put a walbro fuel pump and new fuel filter on my gsr the old pump filter was like half blocked, went a bit better then i upped the boost from stock 10psi to 14psi and it feels like it goes slower and doesnt rev as hard top end? i dont feel any boost or ignition cuts or miss firing just doesn't go as hard as it did on 10psi? Reckon could be leaning out?? This still has the stock td04 turbo, the mods i got is a xr6 cooler and full 3 inch system turbo back

I think you have answered your own question...but the only way to check for sure it with a wide band AFR meter.
the 390cc injectors are really only going to take about 12psi....you might stretch them by raising the fuel pressure with and adjustable reg. Suggest 44psi at a good starting point

Yeah i was thinking injectors but i thought 390cc was good enough but obviously not, which injectors would be a straight bolt on? and would it be ok with stock ecu?

nothing will be compatible....whilst there are a lot of injectors that will bolt in. Anything bigger will require a chip{tune}

Or buy an Evo ecu, and Evo injectors. Evo 1-3 injectors are 510cc so quite a step up from the 390's in the GSR
