I have an interesting dillema that i wonder if some more skilled people can chime in on and maybe give some opinions with EFI Tuning.
Specifically, I would like to know what people think is better for creating more power when tuning. Rail Pressure or Pulse.
I understand that both are needed - but there are usually constraints with a single (but modified) CP3. Bottom line - with xxx amount of fuel - how best to use it to get the most bang for the buck?
Right now, on my LLY, i don't have any dyno numbers to back me up - but i'm believing that more pressure and less pulse is the ticket. I try to maintain 24.5k on the rail, or there abouts with my tuning, as it just flat seems to 'feel' better than when i suck the rail down to 22k or so with more pulse and timing.
I've tried so many combinations, and a DSP 5 switch makes experimenting even easier... but i've found what i'll call my 'threshhold' for fuel. How much pulse i can run to maintain the rail i want, versus how much pulse i can run before < 22k rail.
I am not posting my tunes as there is alot to the tunes, and alot of people have helped me get to the point i'm at with the race tunes in particular. Mostly, i'm curious what people think. I do have 30 over injectors, so i'm thinking thats part of the reason why pressure over pulse seems to feel better. Again, until dyno next week i can't back up either theory.
Thanks for any input! I know alot is open to speculation and not trying to open up any hostilities... Just see what people think, and why.
Thanks!
