Specialty Z got my ROM in (my car was too new when I went in like 10 days ago) and I am confirmed for the Uprev tune tomorrow. Just put some K&N drop ins yesterday too (hoping for mileage improvement more then hp with those) so we"ll see how it goes. Hoping to see 305ish whp. Will update afterward and try to remember to take video.

Awesome, post the update, video and #### =o)

Just got back from the Uprev tune. I'm at 300wp, 249 wtq. My baseline with mods before tune was 291 whp, 246 wtq. Changing between maps is super simple and the valet and anti-theft maps seem pretty cool. I will try out the fuel economy map as well and see if it makes much difference. Will post a video when I have the chance. I am too lazy to scan my dynochart so I will post it when Seb emails the jpeg to me.

So I have a few hundred miles with the exhaust and HFCs now. There is some drone (they told em there would be with the auto), but it's not too bad and you can pretty much neutralize it if you drive it in manual mode. So when driving conditions cause there to be a bit more drone than normal, I just shift to M and am fine. Car feels good, a bit lighter and more responsive. I got the 18" resonators and the resonated HFCs for the quietest option. The car is pretty loud in the morning with a cold start, but is much quieter during cruising and loud (in a good way) when WOT. SO other than the cold start and some rumble in the low RPMs, it's pretty stealthy until you open her up. If you want to be super stealthy, Tony said the HFCs are probably attributig to 50%+ of the noise.

If you don't mind me asking who did your tune and were you running lean or rich before? The tune numbers seem very conservative imo

SpecialtyZ is the tune shop. Tony at FI also said the autos have a bit more drivetrain hp loss, but this is a bit lower than I expected (was hoping for around 305) SpecialtyZ told me the tune was for everything to be efficient and to get performance but keep things safe so maybe it could be more aggressive, but I doubt I will feel a 4 hp difference anyway. I figure a stock A7 usually dynos around 270-275 so picking up 25-30 hp isn't far off from my expectations. I got my HFCs used form a forum member if that makes any difference though Tony said they were functionally fine ( a little ugly from some extra exterior welding not done by FI). Also, temps were probably in the 80s.

The hp numbers from baseline and after tune, vary drastically from dyno to dyno. I was just wondering about the 9 hp gain, it seemed it was definitely on the conservative side. Been talking to Seb about some parts, seems like a great place to me.

The baseline was also from 10 days ago when i went in for the tune but they didn't have a ROM for my car yet. That could be a factor. Rode in Seb's tt 370z. Man, that shove sou into your seat, pretty awesome. 12k though....

I bet that was a sweet ride man. You can always get him to adjust the tune if you want more power. I'm running 26 degrees and picked up 31whp from the tune

Yeah, I'm good with the power. A few more HP will look good in my sig, but I doubt I'd feel it. I think I;m pretty much done for power mods unless I somehow come into a lot of extra cash and decide to go SC.

That is awesome. I have almost the same setup as yours. I went with F.I. Non-res HFC and F.I. TDX CBE SS /w 18" Res.

Do you still have stock intake?

Didn't know SZ opens on Sat. That's where I got my tune as well.

They usually don't, but since I had already gone once and we couldn't do it, he did it on a Sat for me.

Sorry for keeping you waiting Lidat.

Blue was before and red is from tuning.

I just finished installing my HFC and exhaust. Does anyone know how long I need to wait for the high temp RTC to cure for the HFCs? It says 24 hours or longer depending on how cold the ambient temprature is. I can't imagine Tony waits this long while his customers are getting their installs.
Thanks in advance.
