yeah fair call that.
tbh i would sack the vf48 and chuck an aftermarket one on and swap out the injectors and then get it mapped, the graph on min is a sc46+ on low boost, forged 2.5, 3 inch decat, sti inlet manifold, sti top mount and perin inlet pipe. Injectors gave up the ghost at 330bhp though.
May find its time to go aftermarket ecu as well, will be struggling to cope with it. can tell from my boost afr graph the ecu was struggling with the fueling as the boost came in
