    I bought a new set of fuel injectors that's 1050cc. I installed them, but I'm getting a check engine light and reads misfire on all 4 cylinders. Is this because I need a protune or is it faulty injectors? I did a flow test before installed the new injectors and they were fine.
    Thanks in advance!

    *Edit*
    My coil packs and spark plugs are fine.
    I always use premium 93 pump gas.

    Nah man. Pull the pcv tube out of the turbo inlet to create a post maf pre turbo leak. That should balance the afr out a bit /s

    There are a ton of tune changes for injectors but the very least, your ecu needs to scale your injectors down/up/weast by 50%. The ecu can only handle +-25% on its own and generally you don't want it any more than +-5%.
