What calculations did you do, as by the sounds of it you plan to use the existing management, but have made no reference to what the duty cycle is at full throttle on the existing software.
Also if you just go bigger on the injectors you will of course run into problems with fuelling off boost.
Have you considered a pikey motorsport 7th injector setup?
fmu is a fuel management unit. it will give me 8 psi of fuel pressure for every 1 psi of boost so up to 5 psi will still be on original fpr at 3 bar but after than will increase by 8 psi for every 1 psi of boost. then engine will be around 220 hp at 5 psi so i need injectors to cope with 220 hp up to the 5 psi and then after that the fmu will increae fuel pressure according to boost. and my maximum fuel pressure will be 4.5 bar at 8psi boost which should be ok. if i run with 19lb injectors at 7psi i will have to run 84 psi and at 8 psi boost would be 96 psi
so as far as i can gather 24lb is minimum i just hope it will idle its gona be rich but i think it will still run as long as not left idling to long
