The stock injectors are about 21lbs at 14psi. Tweaked APC boxes will usually bring pressure up to 17 or 18 but the knock control will interfere. 24lb injectors are too small for that amount of airflow without at least upping the fuel rail pressure. What are your A/F ratios at max boost? I run 30s in my SPG and I still only push 18psi max boost. Also, you should think about your fuel pump. Is it stock? A 255lph walbro is cheap and good for a few hundred ponies.
