Reviews

  • I have a Quadzilla tuner on my 7.3L Turbodiesel, will these injectors have an issue with my tuner as opposed to the Hydra tuner?

    Cameron Hanson | 4/25/2024

    The stage 1 injectors will require custom tuning. The Hydra is the easiest way to get custom tuning.

  • Will 7.3 with 160cc injectors pass emissions?

    Loren Manes | 10/23/2022

    It would depend on the test and tuning level.

  • Do I order 7 ad 1 ae or are these all th same

    Billy rowden | 4/23/2022

    No, not with performance injectors.

  • I’m currently running a ts6 with stock injectors I’m planning to upgrade the injectors but I’m curious if I can get my ts custom tuned to run larger injectors

    Levie | 7/22/2022

    Yes, it will have to be sent in to get the tunes installed.

  • what is the warranty?

    kyle | 4/15/2020
