How big are your injectors, whats your max pulse width, What are you commanding for rail pressure? Still BIG cp3?
Todd, He means pulse width of the injector not the rail pressure. How big of a pw are you running. 2200,2400,3200 etc.
Seems like your running good rail pressure so I would add more pw to the injector if its not real high already. We have ran as much as 3200pw with 80% injectors on a lb7. The truck seemed to like big pulse width with big sticks.
Like Eric said I just wanted to make sure the pw you commanded is what you get
My stock pumps with 2600pw will hold that rail its not until I get to 2900 that it starts to drop
If you don't want that much pw and timing you will need bigger sticks
bump the pluse width up until you start to loose rail pressure then back it down until it substains desired rail pressure just like simon said. I would also advance timing with the added pulse width.
Thats a good rule of thumb simon. Alot of people are scared of timing. I always ran a max of 39* with my stock injectors and 3200pw. Nitrous and water/meth was the same exact tune. My engine looked GREAT outside the bent rods lol.
thanks working on it. had a great weekend pulling even with the issues. I knew with all the changes there would be some testing. nothing broke & we learned a bunch :thumb:
