Thanks!
btw: What did you have in your car when you got the 392?

Run was done on race gas C16 boost was around 24psi tappering down to 20ish. Also run was with the bone stock 03 evo turbo, no hotside upgrade or mod.... STOCK not Stockish.

What does the HKS DLI do? What does DLI stands for?
Also are you using the MAP conversion?
Why are using 1000cc injectors? Isn't that too big for the stock turbo?

You need a pressure regulator to raise the fuel pressure... pretty simple. You need a fuel pump to pump more gas. You need injectors because you can top out the stock ones without too much trouble. You can help compensate the injectors loss by raising the pressure but that will only help you some. I dont know what I have confused here. Also, bigger injectors one; require more fuel pressure to operate well. Two, sooner or later you will overrun your stock regulator. But your right... I must be confusing the two lol
Without the EMS will make it more difficult but not out of luck. I am quite confident that with tuning the timing and fuel heavily I will be able to pull it off. Im not looking to have a great usable power range here nor will I probably keep the 400hp tune for long... I just wanna hit it I will be racing the car on track and auto-x so I dont want to tune it to the extreme and leave it there. I will de-tune the car once I get a good amount of power and make sure that I have plenty of safety so I can beat on the car for 20 minutes straight without worrying too much. Thanks for those of you that have helped so far

There is no reason to attempt to raise fuel pressure above the factory settings, and you won't get much out of it other than a possible CEL. You simply get larger injectors (if required) and rescale via an external device or standalone. There is no need to change anything else. Likewise, the larger injectors are designed around the same operational pressures as the smaller injectors.

Oh... here is a tidbit to help prove how wrong I am obviously written by a company that has no idea on what they are doing... lol...
"(An) AFPR is used when you install a large fuel pump (Walbro 255 or supra) and the stock fuel pressure regulator is overrun and cannot bypass enough fuel because the internal passage is too small. You will know the stock FPR is overrun when the fuel pressure is over 35psi by a large amount at idle and the A/F ratio is hard to tune at low throttle. It is also useable for an additional tuning variable since higher fuel pressure equals more fuel delivered to the engine, along with the opposite. "

honestly i dont think trying to squeeze the last 20 hp is worth blowing an engine over.
its better to over build the parts and run at a less hyper extensive rate on the engine.
u want this thing to last or u want one Glory down the dragstrip before u have to stick ur feet down like the flinstones

Most high hp cars (Supras and RX-7s) use it for improved high rpm power.
Very good mod that can't hurt to have

Damnit... I found another tuner that has no idea of what they are talking about...
"This brings me to the next modification that I think we are going to need. The regulator. This is going to be needed for high boost pressures to insure the fuel pressure continues to increase as boost levels get high. "

But...changing to and adjutable fuel pressure regulator certainly is worth doing on a car that needs just a little more fuel than the stock injectors can supply. Raising the pressure differential accross the injectors most certainly delivers more fuel to the engine.

I am starting to sound like a d1ck and thats not what I am trying to do. My point is that the regulator could be used as an additional form of tuning if neccessary. It also makes it much easier down the road to do things like run turbos at 30psi. Im not trying to be mean to anyone here but when people try to make me sound like an idiot I will make sure they understand I am honestly not all that dumb (Not smart by any means either). Sorry if I offended anyone but please, I was just looking for help, not people to tell me Im an idiot.
