Tuning by rail pressure

[JJPage]

Can anybody who has done this on a dyno, tell me, how low can I let my rail pressure drop, before I will start losing HP/TQ?



Trying to do this by SOP just does not make alot of sense, as everything just happens too darn fast!



Thanks, Jess



Sure do miss the old SPELLCHECK BUTTON!

At the risk of sounding ignorant, where's the "go advanced" button?

when you press the quick reply button to respond to someones question , right below the square where you put your reply look down and there is 2 buttons , its on the right , go advanced , just press on that:-laf

I'm not sure what that button is either but to the upper right of the test box on your reply there is ABC with a check mark under it. That is the spell check button. I circled the button.

Yes, I tried that and I also downloaded "iespell.com" but I get nothing!



Back to the original question, how low can I go! (12,000, 10,000 ?)

Anybody? How low does your rail pressure drop before you start loosing hp/tq? Or is any drop at all effect performance?

For the best power try to stay around 20,000psi, if it dips to 18,000 you're still ok just not where I like to see it.
