Performance Injectors+ FPR, How do you control them??

[joker2]

OK, here's a question for the tech heads on the board...... Our stock injectors flow at 240cc, what happens when you upgrade to a 310cc injector??? I know that you have increased the flow rate but can you control it by adding a Fuel Pressure Regulator(FPR)??? What I'm getting at is that when you run your stock injectors and increase the fuel pressure, you're adding more fuel to the mix so I'm trying to figure out what's the difference between the higher flow rate injectors and just increasing the fuel pressure???

you will need something like a apexi S-AFC, and you might need to upgrade the fuel pump.

higher flow rate will let you run less fuel pressure to get the amount of fuel desired vs cranking it up to get more pressure for more fuel in the stock injectors. Neither is a good idea on a stock ecu, they usually run way rich... which can be helped with an afc but its really not the best fuel managemant.

OK, I see what you're talking about........ Thanks......
