I've been running these for a couple months now on my d15b set at 9psi off the wastegate spring. It's making 206whp. My tuner says the injectors are fine and that he would increase the fuel pressure. I've been driving the car off and on for a couple months now with no problems. What do you guys think? Should I get bigger injectors?

 

 

wait, what?

 

raising the fp will allow you to make a little more, but why push it on the 310's?
