    Exclamation IFR values for 43 lbs Delphi shorty Injectors? HELP messing up Tune 17113739 - 251760

    Hello, i am tuning a 2 BAR SD on a 2005 Silverado that has a Maggie S/C and throws around 8psi of boost, i set all the values to 35 but is running to lean even if im trying different AFR or 12 or 12.5 and runs with out any power at 12 AFR even if its richer, i am having trouble tuning for PE and VE table because i dont know the IFR for these injectors, part #'s 17113739 - 251760 and this is the link to where i bought them

    A 2005 truck is a returnless fuel system so the IFR vales should be on a slope, not a straight line.

    Are the injectors rated at 43 psi or 58 psi?

    The info you need might be on the list that you get with Greg's DVD??? I havent seen the list of whats included.
