    Injector data scaling with lower fuel pressure

    I bought Fuel Injector Clinic 660cc LS3 EV6 style injectors some time a go. It seems that these injectors are too big with OE 58psi pressure for 400RWHP N/A E85 output. FIC injector data tables are refering to 58psi pressure. I would like to lower my fuel pressure to 29 or even 43.5 psi. I have adjustable regulator with return line. Can i scale flow and offset tables by half with 29 or 3/4 with 43.5psi? Is it offset tables linear? 29psi looks like optimal pressure for this output. Is there something why i should not use so low pressure as 29psi?

    I'd try leaving the all the other data the same and just change the flow rate information to 43.5 and run that pressure.

    If you are still running into rich idle condition you will want to lower the min fuel milligrams by half or more to help.
    2016 Silverado CCSB 5.3/6L80e, not as slow but still heavy.

    If you don't post your tune and logs when you have questions you aren't helping yourself.
