Max RWHP on stock fuel system? I'm mainly concerned with the intank pump and lines up to and including the rails. I'm at 400RWHP right now but was thinking of adding a few more mods. 
How far can the stock system go?

I am still running my stock fuel system as well. When I use a wideband it shows that I am running nice. My injectors are almost at max duty cycle and my SES lights are actually saying both banks are running lean (which is most likely an O2 sensor).

With 96lb/hr injectors I made a lot on a stock pump, the PW was really wide and pressure really low though. Its a bad idea, I had to adjust my tune almost every other pass to maintain a 11.0-11.5 AFR

Well, I'm at 400 now and I only plan on adding about 100 more or so to the wheels. I just wanna be sure the in tank pump can support it.

There are exceptions to every rule, but we usually suggest a Racetronix pump kit between 400 - 440 RWHP. Think of the pump upgrade as an insurance policy, it only takes one time for the engine to lean out and it's over, so why risk it?

Id say your probably gunna need a new pump for what your planing. but a new pump isnt that bad if you put in a trap door and if you dont want to do that i will help you drop the rear and put it in that way.

Like I said ealier, its not worth the risk - for a $100 part and 2-3 hours labor of your time to install it, well worth it.
Or you could blow up a forged motor like me
