Message: [QUOTE="madman1234509, post: 1066512, member: 3910"] You will need to decrease rail pressure, as mentioned. It has not been proven that deleting your fuel bowl will increase your ability to maintain rail pressure. Also, it has not been proven that having ported fuel rails do anything at all, besides potentially make trucks have surging issues. I run twin pumps and 100% nozzles with stock fuel rails, no issue. Had ported fuel rails on my 08.... truck had surging issues. The major factor in not being able to maintain rail pressure is 1. Health of the injection pump, a healthy pump is close to maxed on a high pulse width tune with stock injectors. Health of the stock lift pump, or rather..... having a quality lift pump system that isn't maxed out on our trucks like an airdog. Some people like their 15% nozzles with a stock pump. I personally wouldn't risk the premature wear of my hpfp just to run them and have minimal gains. [/QUOTE]
