Fuel system question.....
I know that someone has asked this before, My computer was being stupid and wasn't loading up my search for the stock fuel system. Anyways, how much horsepower or how much can I do to the car before I have to upgrade the injectors and fuel pump? I know I have to have an upgraded ECU to remap the fuel, but how far can retuning go until bigger fuel pump and injectors are needed? I just want to know because I need new turbos and I was thinking of getting slightly bigger twins. Granted I have a downpipe, let's say an upgraded ECU and a slightly bigger intercooler. Thanks for info.

Once you start increasing the boost you will need to upgrade the injectors and pump. It would be nice to get a PFC so you can monitor the injector duty cycle. Right now you don't need to upgrade the fuel system.

well, I'm not increasing boost just slightly bigger turbos. There not much bigger than stock, but they are 400 HP type turbos. Does this change anything? And I still need an upgraded ECU right? Or no?
