    just want to figure out where i want to be with the 270cc's, once i get my AEM fpr back...

    stock injectors were 240-250cc... so i need to come down about 10% od stock idle to get rid of this friggen code 45 every other day...

    damn that CEL is like the stare of death... i get freaked out everytime i see it...

    what would be the ideal range to be at during WOT with the 270's and 10psi boost...?

    i think the guys running 310's are at like 75-80 at WOT...? so i think i would need to be at 90ish...?

    any help woul dbe appreciated...

    Set your static pressure (no vaccuum) at 45-48 psi... and your rise rate should be about 4:1. So, this means that if your idle settings are as above, your peak fuel pressures (at 10 psi boost) will be between 85-88 psi.

    That should get you pretty damn close to where you need to be.

    Good luck.

    i should make that adjustment to the Cartech... with the vacuum removed...?

    and i just talked to Cartech today, and they are sending me the restrictor that my installer apparently lost, or just didn't know what it was and never gave it back to me, or it was never included...? who knows...

    with the restrictor in place on the 2025 what is the range of the rise rate...? i thought i read somewhere it was 3:1 - 7:1...? or something close to that...?
