Conversation Between trekbasso and Tugly

New injectors are undeniably "crisper"... even my wife noticed it after I did the swap. You can hear the solenoids snapping under the valve covers (it's like a perpetual buzz test), which I find interesting: Anytime you can hear the solenoids over the injector, the injector noise is under control. That being said, I still have one loud injector I'm going to swap out with my 9th injector. They all run beautifully, but the truck is so quiet I can easily pin down a single injector knock - and where it's at (#7) with the valve covers on.

Hi Rich. So, noticed in your post you mentioned "new sound" vs "reman behave". Were your new injectors quieter with the same tuning? This latest towing thread is really hitting home for me, and I hope to be able to change a few things in the next few months. Injector noise is worth chasing for me whenever I pull the trigger.

Thanks for the DP Tuner Rep! It's appreciated.
