Those are my exact reasons CoHPhasor! I dont understand why tuners are not able to create a tune for these injectors. It says on WF's website that "Standard tuning practices as you would have for the NISMO or PE injector upgrades!". But i also dont know much about tuning (trying to learn everything i can). Does driven authority not offer a latency chart for the injectors they sell? It also says on their site that their kits come with "Bosch EV14 LS7 style injectors".
