To run 1.5 bar (22psi) i would advise you to run larger aftermarket injectors to flow enough fuel, so you wont lean out.
Make sure you have good cooling for the engine and intercooler at those boost pressures.

change to either 7mgte supra injectors that are 440cc but even they may be too small so probably 550cc series 4/5 rx7 13b turbo injectors

edit: the stock gze injectors are only good to about 150rw/kws they are 365cc

You will definately need to run larger injectors when talking about that amount of boost. Try and pick up a cheap set of 550cc or 600cc injectors. Your always safer going bigger when it comes to your fuel system!!
