if your concerned with your engine and k's with that setup run 15 psi. you would be more than happy mate

lol yeh that might be ok, but it might knock like a $2 whore if its not tuned to that, and if the afm or inj cant keep up, it should be right but saying that how much do you wanna risk your engine

so with all your mods and the soon to be ECU using a MAP sensor i wouldnt even reccommend starting it until you upgrade the injectors. (that is an overstatement but its not far off).

depending on the drivability you're after then choose what injectors you need (make a compromise between the open/closing time and impedence etc). the people you're buying the ECU from will be able to hepl you with all this.

i would say that roughly 700cc injectors will be more than adequate to drain your tank (550cc will probaly even do...)

you may also need to upgrade the fuel pump and have a surge tank too with that size (700cc) injectors. (unless youve already done this, i didnt really read your 1st post very well)

however im not an expert and i would strongly advise to talk to the people tuning your car about what injectors you will need.
