not sure what info you want but i don't have the 550 injectors but do hold the record for the world fastest crossfire.
if you have a afr gauge, don't go any higher than 12.5 afr reading. don't forget your fuel pressure has to overcome your boost, air pressure into engine, to make the engine run great so if i were you, i would get (if u don't have one) a afr gauge. and set my fuel pressure with that. hope that helped jim
