lmao.. yeah im using corn dog gas. Like I said I ran so I could datalog and adjust the fuel map, i ran just once like i promised myself so I wont wash my piston rings.. Im not so in hurry to get power, the my goal for my stock motor is for learning.

Well i had my base pressure set at 40, 50, 60.
It all depeneds on what you need!
I found it easyest to idle car adound 50psi!
play with it! its 1:1. So at base pressure of 50. at 5 psi it would be 55 PSI.
Dont be affraid to test it out

yeah I got that 1:1 thing concept already, im just thinking maybe the bigger your injectors the more pressure is better for better atomization of mixture.. I started with the stock 45psi and got it to idle good but then went to 55 to get more fuel while on boost and tuned it to idle great.. lol ive been wasting too much fuel playing with start up and idle, now i have to redo when my injectors come in

^^ its less restrictive than that walbro fuel exit, unless you have a way of modifying that walbro exit i dont think it would matter. In fact just IMO, from that very small walbro tip then a sudden transition to a significantly big fuel line is more prone of fuel pressure fluctuation
