Low dyno numbers
Took my car down to a dyno day a couple of weeks back and was disappointed by results, 374 whp and 444tq was best run, intercooler pump was replaced couple months before the run, dyno jet
#3
i believe for a dyno jet it shouldn't be reading that low because that equates to around 449hp at crank (rough estimate) but the e55s were underrated so it should be making around 500 hp crank stock I believe, car has 70k
#4
If this helps you....my stock 06 wagon with 75K miles on it dynoed at 389 HP and 438 Tq on a Dynojet.
15% loss puts it at 447 HP and 504 Tq
18% loss puts it at 459 HP and 517 Tq
Given the age and mileage...seems within the range.

I heard this car has a 20% loss and all I do is 374x1.2 which gives me around 449hp crank (rough estimate) and on top of that the car is underrated so idk just worried something is not right
#7
But the torque figure seems about right, just the hp that's bothering me, I'm trying to get her as healthy as possible before mods, promised myself mods would come only when she's at 100% health

I'm not too sure as the pumps are factory and I have not done the fuel filters but I believe my fuel pumps are on there way out because it has stalled twice within 2 weeks on morning start ups and my warranty covers fuel pumps so I'm basically waiting to change out the pumps

This place is a joke.
Check for fuel leaks under the back seat- read about the extended warranty for the free fuel tank/pump/filter replacement. Fill the tank up- if you smell gas afterwards you may be eligible for the free replacement.

Never noticed fuel smell ever, did 05s still have that issue?

If you're stock, doing it in 4th, it was the third pull. You've probably heat soaked a touch and have started to add some fuel and drop some timing. Wouldn't get too sexed up about it. Hit the track. Run a low 12 high, 11 at 118-120 and you'll be in the right range.

A few things:
1) Your dyno line trajectory looked like a mini seesaw. Something is not right but don't freak.
2) If no one has told you buy some diagnostic equipment. I am no expert on it so search the threads...
3) If you don't like the #'s let the mods begin!
*******HOWEVER************
4) MOST IMPORTANT; enjoy the car. It will never dyno high enough, run ET's as low as you want, trap as high as you want, or etc, etc, etc, etc.
Plus, someone will ALWAYS be faster (often in something that costs 1/4 of the price of your car). It is just the way it is...
