Who has done the mapping if you don't mind revealing it? With that list of hardware fitted I would have expected a bit better result (520 ish) even for a DNWA engine.
I have recently been chatting with several guys who have a wealth of experience tuning Audi's and they both say that the DNWA engine has had some internal changes (exhaust cams, compression, routing of intakes for emissions was mentioned) as well as the OPF's fitted to the exhaust system. I guess over time that tunes will be refined to produce more power. Fuel octane rating is key factor for the DAZA engine.... it loves high octane fuel and produces really good numbers if you can get good amounts of air through the intake. I suspect this is also true for the DNWA engine and maybe the cause of the inconsistent drag results for the races we see on YouTube channels.
From your list of hardware the only part that I would question is the Eventuri as it's still unproven (the people that make and sell it will always say its brilliant) and is really intended for hybrid or big turbo conversions that benefit from massive airflow. My option would have been the tried and trusted IE intake or the new Unitronic version. The mapping for all these parts would need to be good too. Have you tried getting it on the dyno at MRC (they now have switchable mapping for DNWA engine)?
The tuning was done by Wilderness tuning and they had been great actually, aside from the power. Yeah, 520hp and around 700nm would be something I would be okay with, even though I expected to see around 530. I've done the research on the parts of the DNWA engine and there are differences in part revisions mostly. OPF is bypassed, so it should not be the limiting factor anymore. When you say compression, what would that be the consequence of? Different pistons, or intake routes or both (sorry, not a mechanic, but still trying to understand )?
Of course the fuel octane has an effect, I always put in 100ron we get, but just to be sure, I will also try different brands and will get it on a dyno again, just to exclude this as a potential factor.
True, Eventuri is still unproven, but the MAF should still be high enough to get that hp, I am sure of that. Unitronic and IE don't officially support DNWA yet, as they are US companies, so tried to avoid them. However I am not spending another thousand, just to test out if we get 10-15hp more, since all those intakes are very expensive. If someone else will go with them and get higher power, then I would consider changing it, before it's just not economical. Maybe I could try Forge's system and stock filter housing? If we only make 10-15hp more than the stock intake on other DNWA cars, not sure..
Sadly I can't get it dynoed at MRC, as their closest authorized dealer is about 1k miles away from me. I saw their map switching, looks good, but I guess I am out of luck.
