Not trying to beat on any single product, please dont give OPINIONS. I am simply looking for dyno or track proven results. Has any one done a side by side comparison of any injectors? example: F-1, Industrial injection, DDP and the list goes on. They all use there own techniqe to build all of there awsome product and i have great respect for what they all do. I currently run a set of F-1 3.3's myself. They work great. Just curius to see or hear of anybodies trials.
