Alright guys, need some first hand knowledge. I'm wanting to put some new injectors and a new turbo (II PS62/14) on. It's a daily driver truck, and I want it to be very streetable. My goal is a D/D with 600hp. I don't want to buy DDP3's now and later have to buy 4's to make that happen. But, I want it streetable. So, my question is: Would the DDP4's be too much injector for a D/D truck, and I should go with the DDP3's?
