I know the goal here is to get the same effect without spending $$$ on hardware but damn I'm pleased

I have the same thing and the crackles/pops sound nice.
Wish it was a bit louder though.
+1

I haven't forgotten about you guys, customers are priority first before playing. I made some final adjustments that I need to go out and test first. First Beta map will go out to J. Dub since he has the most promising exhaust setup IMO . If he gives me thumbs up on it then Ill send the beta map to the second beta tester that I haven't chosen yet. Still sorting through emails atm.

No rush D.

Also for those wanting to know my exhaust setup.

AE exhaust, VRSF DP's, (so no cats at all any where)
Then I cut out the mufflers on the AE exhaust and welded in straight pipe.
No resonators, no mufflers, lots of drone in 6th gear @82-84mph. And rasp in 5th gear @ 61-66mph.

Exactly, I can only take a call when I'm coasting

Supra2k6 · 03-14-2016, 10:54 AM

Email sent full exhaust with welded x pipe stock cats until warm weather.

Owww snap!

I think it's awesome you're doing this btw, I know this must not be a high priority for most tuners... but for some reason I like the sound too. Doesn't have to be as overly prominent as the n55 /w mppk, but somewhere in between a stock n54 and that would be freaking awesome. Will definitely opt-in if this becomes an option!

Its not going to be "like" the N55. I would like for it be the N54 with its own unique capable sound.

The N55 has a high pitch aggressive sound with the right mods, well, the N54 should have a low deep pitch aggressive sound like a panther growling. So yes an in between sound is about right.

There are other tables we don't have access to yet, so I've done as much as I can to see if it would make a difference.

Aqid · 03-16-2016, 02:56 PM

+1 for growling panther

Awesome, I'm excited to see what the 3 beta testers say about it. Definitely gonna follow this thread.

joeinsd · 03-16-2016, 11:12 PM

But doing this will disable any power maps? I'd probably pay a bit to hear more of the burble and pop on my stock exhaust, but will have to think about it if it's flashed over power maps. Hmm... here to see how this plays out.

youtube jaguar f type R exhaust burbble or the lamborghini huracan with sport exhaust (not the base model exhaust) Those two sound like an N55 on steroids.

in these betas, yes. But I bet once I help him dial these in, BuraQ can then implement them in his custom maps he charges for.

Update, I have gotten my map from BuraQ and I flashed it yesterday. I will be getting him his logs he requested this evening.
Things to consider are that I'm on an alpina TCU flash.

Cloud9blue · 03-17-2016, 02:43 PM

It is just extra fuel being dumped downstream and igniting in the exhaust... If you have jb4, you can adjust DWP and set it to FUD98 for similar sound. helps if you have port or throttle body injection that dumps extra fuel in the manifold as well...

But then those who want to keep driveways clean will have to deal with this issue correct ?

Need this! I'm thinking no Cats and full exhaust will open up the noise more.

I can assure you I have the loudest stock turbo N54. I have true dual pipes. One from each turbo all the way back. no X-pipe or H pipe. No mufflers. No resonators. But I agree, the Jaguar F type and huracan sport exhaust both have great off throttle crackles, burbbles.

I also tested the beta PPK N54 map from BuraQ. I am sending him logs this am now that they uploaded to datazap. Cliff notes. The off throttle gurggle didn't happen. But I am not hopeless. This is the first beta of BuraQ's attempts.
