It makes 450 hp before you do.
And I am making 500+ on meth with IDC to spare.

I never turned it into an e-peen contest, you just said a stock RS4 is weak, I just said that you have never driven one. And I was right
As for that dyno chart - there are a lot of things wrong with it - I've seen it before, and you can choose to believe in fairytales if you like, but this is irrelevant to this discussion.

I'm curious about that RS4 dyno. So the red line is dead stock, right?  Did you happed to be logging at the same time as the stock run?

Your RS4's fuel pump is probably dead or on it's way out.
I've run 20 psi at 95 IDC to redline on mine for close to a year, before I fitted a meth kit, but I have a 044.

312whp is 100% stock on RS4. Or there is something wrong with the car.
In fact if you maxed out IDC at only 18 psi, there is 100% something wrong with the car.

And I can surely say this, because I have mapped a few of them.
As for your dyno numbers - you don't make 500 crank nor 450 whp with 5-12 timing at the boost.
Instead of king kong banging on your chest, an experienced tuner would look at the numbers, realize that something is a miss and then inspect the base settings on the dyno that were made for that run.

However, this probably did not even occur to you. Nor do you care as long as you can wave your e-peen around.
I wonder what my car would make on that dyno, as I am running more boost and more than twice the timing than you are - on the "weak" stock injectors.

Well, I've tuned several RS4's and none of them ran out of fuel at 18 psi, unless you ran something like 10.5 AFR.
I run about 11.8-11.7 AFR on them to redline and there is enough room to enrich to 11.1-11.3, as that is what I run in BTS. 19-20 psi.
My point is just that something is wrong with that number. Either it was made in a low gear, the dyno had incorrect loading or there was overcorrection for some reason.
I've mapped enough 2.7T that I know they don't make that power at 5-12 timing and boost.
My RS4 runs 14-25 timing at 1.7 taper 1.5 and I would not rate my car much over 500 crank... Then again, I have up to 550cc of pure meth going into the engine (50/50 mix and 1100cc total flow.)
IDC stable at 95% and no EGT issues.

I am not trying to have a dig at you, I am all for people making power, it's just to me there is something wrong with that graph, and I don't like you saying that a stock RS4 is "weak" when clearly there was something wrong with fuel delivery on that car...
