Dyno results not what I was expecting
have the Eurocharged Tune: http://www.eurocharged.com/products/...se-model-451hp
With my car having the P30 package I was supposed to be sitting at about 540 HP. I hit two runs right at 389 WHP. The operator didn't think that made sense at all.
The below company did stock dyno's on the P31 and the non-P31. My car was sitting right at the stock numbers for the P31 package. But that conflicts from the datacard that I have for my car which clearly states P30 AMG performance package.

540 quoted is crank which is about 450 whp, but that is on a dynojet, let us know what Dyno you used, if it was a Mustang (known as the heartbreaker dyno) you could be seeing under 400 with a tune.
some dyno's are considered "heartbreakers" some are not regardless of brand...but mustang and superflow dynos always read lower than the rest.
also i'm assuming you put your car in dyno mode within the cluster menu?

A 60+ Whp discrepancy between our cars can’t be because of which dyno we used. That’s way too big of a gap.
Identical cars. One on a mustang in Denver and another on a Dynojet in NYC and I wouldn't be surprised at 100whp difference.
As mentioned above, dynos are best used to measure gains/losses. The track (60', ET, Trap considering DA) is where you'll really find out what is going on.
Sounds like your car is just fine to me. No CELs, running smooth, etc.
I don't really agree with some of the above statements though, sure you can't expect your numbers to be exact same as a different car on a different dyno but these cars still to seem to dyno around 400whp with the performance package stock and what, like 440ish whp with a tune? It would be different if you were within 10whp or something , then I'd agree with some of the above statements. And it's not like you were on a mustang dyno either, which tend to read on the lower side. Those hp numbers are what I'd expect from a stock car. This is just based on results everyone seems to get on average, give or take a few hp, on this forum.
It's the middle of summer...none of our cars are going to perform that well on a dyno. Hell, mine dyno'd 500 on a cool day in the Spring, but I am sure it'll be a lot less than that if I dyno now with IATs well over 100 degree's F. On cold mornings or at night though....MMMmm...yummy.
In other words...your car is fine. Go hunt down some (stock) Audi's.

Completely different and while i can only go on my butt dyno, its a huge difference now. I am curious as to what was different between file 1 and file 2.. I also am going to wait some time while the ecu does re-map over some time for a final analysis.
