i have a 05 truck 5.3 ls1 intake . i installed 26 lb injectors with ev6 plug and the motor runs rich at idle.the injectors were rated at 26lb at 43psi. could this be to much injector at the 58psi? what would you recommend for injectors?i am thinking about putting in smaller injectors do you think 19lbs ford injectors would work better?i need to stay with a injector set up with the ev6 connectors because the wiring harness is set up this way. thanks bob

Was the vehicle tuned for the 26lb @43psi injectors? Stock '05 5.3L injectors are 24.7lb @ 58psi (non flex fuel). The PCM must be tuned for the different injector size if not previously done.
