sup ya I just received my h22 290cc injectors in the mail. One of my stock LS 240cc injector is failing so what the heck,why not go alittle bigger. I have my fuel psi set at 52 no vaccum as of right now. When I change out to the bigger injectors I figure I would have to lower my psi, is this correct. Our does it still put out the same amount of fuel cuz it its a "regulator". I shouldn't feel any different in powr correct?

 

Yuor gonna need to turn the injectors down if your gonna want the same amout of fuel. The best thing you can do is put the car on a dyno adn set the rgulator that way.

 

uberdata is your friend, you dont need any extra stuff just a uberdata chip with adjusted fuel maps for your injectors, run a serach for Uberdata on here for more info
