stock injectors + higher boost
I was under the impression for a while that the stock injectors were somewhat sufficient enough for 5.5 psi. This is not the case, atleast from my experience.
The power graph on the 5.5psi + stock injectors pulled (however very lean up top after 5800rpm), but you could see that the power graph was sketchy, not smooth, almost like the ecu was pulling timing very slightly.
What I think now is that if you are anywhere near 5psi or above, you should definitly upgrade to bigger injectors (Supra NON turbo or similar).
