    Injectors for LSA supercharger install quick question...

    Piecing together parts for an LSA supercharger install on my L92. I don't have injectors yet and was trying to decide between the stock LSA and Deatschwerks 50 lb/hr (16u-00-0050-8)

    Looks like the stock LSA injectors (stock 2015 ZL1 tune data shown) flow around 53 lb/hr at ~58 PSI

    And the Deatschwerks data is 61 lbs/hr at 58 psi.

    LSA injectors are selling used for ~$300 right now, and the Deatschwerks are like $500 new.

    Seems like this would be a way to give me a little room in injector DC without hitting my 63 lb/hr limit on my E38 ECU and having to do the half flow double stoich hack. Or am I missing something? I'm starting with the stock pully and with the smaller truck crank pulley I'l be at 5-6 psi. I don't ever see trying to push this blower more than 9 psi as I don't want to deal with the heat plus I'll be on a 6 rib belt.

    Thanks!

    I'd probably go with the larger injectors.
    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.

    definitely go larger. you want to have room to increase, not have to swap injectors again later if they won't cut it.
    and the scaling isn't a big deal.
