    DeatschWerks 42lb/hr fuel injector help

    New to Hptuners working on a stock 2014 5.7 Hemi challenger the fuel injectors need to come out has anyone setup
    DeatschWerks SKU: 13U-00-0042-8 Matched set of 8 injectors 42lb/hr on a stock 5.7 , they are bigger injectors than
    stock and need to be tuned I have watched the RecklessMotorsportsUSA on injector pulse width tuning and the goatrope video however still a little confused was wondering if anyone that has set up the DeatschWerks 13u-00-0042-8 on a stock 5.7 could share their tune , I am just looking for something to get me up and running , and can dial it in from there.

    Yes I know I could just put in oem mopar injectors and for the most part be plug and play however , the cost on the oem stock injectors is considerably more, and that is $ that can go to other areas.

    Please excuse my noobish question , new to hptuners, not new to building cars sometimes my 52 year old brain needs all the help it can get when it comes to learning new areas , help truly appreciated

    Be sure to log fuel flow rates, fuel masses, and injector pulse widths after entering your injector data and loading it up in a tune. I have found more often than not, that Deatschwerk's injector data tends to be quite a bit off from what they usually are putting out. Just FYI.
