Stock fuel system is good up to 250 HP or so. I had a street port, exhaust, and intake on my S5 NA and it still ran rich.
No point. It will NOT make the car run rich though, the TII's and the N/A's have the SAME fuel rail pressure.... the TII pump is juts capable of a higher volume....
No need unless you are heavily ported, with every bolt on. .. and that's still questionable, but a good safetly measure.
Built up N/A's just don't need quite as much fuel at WOT as a TII (one making the same power) does. Especially if you are tuned leaner with an S-AFC. The N/A's run leaner.

Funny, because my N/A runs out of gas at 8100rpm as viewable on the a/f gauge. I have a big street port and every bolt on as you say... Pulls strong up untill it leans out and power cuts out. Even with the S-afc fattening it up at the higher revs, it simply cannot deliver.
Thats a pretty bullshit theory saying that the TII needs more fuel at the same power levels than an N/A. True the TII tends to run a hair richer, but not enough to equate to the vast differences in the two fuel systems. 550cc injectors are roughly 20% larger than the 460's that N/A's use. Getting an N/A's power to equal that of a TII will take a substantial increase in fuel system capacity. Running 4 460's at 100% duty cycle is not accurately stating that the system is capable of the HP.
