injector upgrade

[Ryze268]

Not sure if you guys know but I have embarked on boosting my 2NZ-FE, I have in 1ZZ injectors however while tuning with the AFC Neo, we're running into lean spots while under boost.

My tuner said that I should upgrade my fuel system but that's kinda expensive (I plan to do it, just can't right now). He then said bigger injectors and a bigger fuel pump should help. While looking up new injectors I found these:

They looked weird compared to regular injectors and I was reading up on them, turns out they're AR engine injectors.

The Tumble control valves, along with new 12-hole high atomizing long-nozzle fuel injectors, reduce the amount of fuel adhering to the intake ports and therefore maximize fuel economy and reduce harmful emissions.

Do you think these are worth having?
