I just installed (Jan 2016) a set of DDP 50+ HP injectors in my 2002 LB7. All I can say is WOW! The engine runs like it did when new, (195K) miles on the clock and counting. There is a difference having the injectors tuned to match. You can feel the HP gain with your right foot.
Last time I replaced the injectors with OEM from GM but now I know they weren't right, the engine was noisy and the injectors only lasted 60K miles. Hoping for 150K miles from these DDP injectors!
