Hello, can anyone point me in the right direction as to why my injector duty cycle just dropped like crazy around 5k rpm? It only started once I upgraded to a 20G turbo.
I had the stock fuel pump and it did the same thing so I swapped it to a AEM 340lp. I had 550cc injectors and swapped them to 750cc and it is doing the same thing with the upgrades. I swapped coils and plugs and the same thing. Oem coils and ngk plugs.
