My only point is before we all just assume the injectors are the problem, more research is necessary. Our injectors are HUGE as far as modding goes, I don't know of many cars that have bigger injectors, even on big hp V-8's. If anyone can name some cars with bigger than 42 lb. injectors please let me know.
Any high HP FI motor 4 cylinder will have larger injectors, and a lot of 6 cylinder ones as well.
I'm pretty sure the stock injectors are 34.8ish lbs but run at 44ish due to the 4 bar fuel pressure.
