Blitz Access/jdm 440's?

[91T breezen']

I have a Blitz ecu, that is tuned for the USDM 550's. I am planning to use the stock twins for quite awhile, (unless they decide otherwise!) and, I would rather just utilize the JDM 440's, because of the non-fitment issue (tabs) and the wiring hassle with the resistor relay. This route would also allow me to be able to go back to the stock ecu if I had to, without too much hassle. I have an SAFC II, and running 17-18psi, still have about 16-18% fuel pulled out. If I was willing to immediately re-tune the car, can the JDM 440's be safely used with the Blitz ecu?
The injectors will be completly cleaned, flow tested and balanced before installation also.
Thanks.

With a retune you should be able to add enough fuel to counter for it having smaller injectors. Be careful under boost at first though!

Thanks, yes I will! My friend is running mid 400whp range with his 2jz, and still has to pull alot of fuel out on top! They also used to be a MKIV crazy here, who was AEM tuned (stock fuel w/ methanol inj) who was in the high 600hp range and still good on afr's. With that being said, I know that the 440's can supply enough fuel to keep it safe, just wondered mainly about compatibility with the Blitz ecu.
