Yeah I have the same mods but no heat exchange too. Had my local exhaust guy fix the the awful sound it makes when you put on downpipes or High Flow Cats.

I'm looking at a tune too but I'm thinking getting a LSD first.

I got some Michelin pilot Sport 4s but that was a long time ago and need a new set soon.

Tyres, Tune, Heat exchange and LSD. Money money money 💰 💰 💰

Mate , I have the same issue right now with the exhaust noise , if you can tell me what your local guy did , I'll talk to my guys and see if they can do the same. Power is good but it just too loud when put it down.

Good to know, the factory pipes have an X too

Assuming you are starting with a red sport/400r with the factory akebono calipers, you will never need to upgrade the calipers/disc/pad size which is good news (mine really could do with a rebuild though, the auto braking seems to be hard on them). They are the same as the track spec 370z when people can't find a parts lookup.

Because I am/intend to tracking the car, I put race spec discs on it (DBA5000 series which are 2 piece) but for street use I would stick with factory until they need replacement, then put on slotted DBA4000 discs

Pads I can't help much, I went with winmax street/track pads but they are not what I would choose for street use; they have great bite and never faded on the track, but are dusty as hell

Fluid should be changed if you don't know when it was last done, I use Motul RBF600 and change it annually.

That setup is sure to be fine for any power level you throw at these for spirited street use. If you are doing full on racing of course sky is the limit depending on exact needs.

Thanks mate , I'll let my exhaust guys know to see if that addresses the issue.

Thanks Duncan , they are the akebono calipers , for discs I might just look at getting the same size but possibly slotted units.

2 spots that my exhaust guy joined the 2 pipes together

Made a big difference. I'm now able to live with it. I can make it louder if I want by removing the HKS caps.

Looks like a good fix , I might look into a HKS unit in the future but I had me exhaust guy look at it , apparently the resonators in the FUJITSUBO - Cat Back were hollow (decorative resonators ) , so he removed them and put in high flow resonators , that's made it little less aggressive sounding in low RPM's.

Good evening SAU team , just a quick update on the 400r , just had the guys Lush Auto Spa (https://lushautospa.com.au/) do full paint correction and ceramic coating(Exterior and Interior) pictures look great , I'll be picking it up tomorrow.

Highly recommend Lush Auto Spa for anyone who wants their car to look its absolute best.

FYI:

Racebox RE7R Custom Tunes Released!

https://goracebox.com/.../2017-infiniti-q50-q60-re7r-tcm...

FOR GEN 2 (21+) VEHICLES, PLEASE SEE NOTE AT BOTTOM

2017+ Infiniti Q50/Q60 RE7R Transmission Tune on EcuTek

But whomever tuned your car is the tuner you should go back to, AMS, Sonictune or BT Tune....

**Duncan** · 2025-08-28T03:45:42Z

Very good news...I contacted Racebox about it last night. My car is a 2016 so remains to be seen if it is compatible, requires a TCU swap, or is impossible.

At this time, no. No ETA either 2016-17 models. You will be able to purchase and install a 2018.5+ TCU though

TCU purchasing and pricing info!

As we near the release of TCU tuning, I am going to answer some questions I get asked often.

What do I need for TCU tuning? At this time, you will need a 2018.5+ TCU to be able to tune. If you have a 2016-to early 2018, you will need to replace your TCU with the newer version. One good way to know if your TCU is good is if you have auto upshift in manual mode in 1st gear around 6500 rpms. If your manual 1st gear goes to 7k rpm and will hit the rev limiter unless you shift, you have the older TCU.

Why do I need to buy another ecu license/phone flash if I already have it on my ECU tune? The TCU is its own computer module. It is completely separate from the ECU. Because of this, you will be required to purchase a TCU license and, if your tuner has it, the phone flash license required to tune it via phone/bluetooth.

Do I need TCU tuning? TCU tuning is NOT required. However, the faster your setup, the more it will assist in track and dragy time consistency.

If I’m ECU tuned by (tuner A) can I get my TCU tuned by (Tuner

? Yes, since it’s a different module and a completely separate flash, you can have two different tuners. However, it is highly recommend that you have both tuned by the same tuner. For me, my TCU tuning will directly complement my ECU tuning style and features and running my ECU and another TCU or vice versa MIGHT cause some issues. At this time and for the foreseeable future, I will only be tuning my current ECU tuned customers TCUs.

I have a SYVECS AWD controller. Do I still need it? Yes! The AWD controllers main job is to control your AWD system. However, with TCU tuning, you will no longer need the auto-shift function as that will be done through the TCU. The AWD controller will still be very beneficial for racers looking to maximize traction on the launch.

Shift schedule changes: holding gears longer at lower pedal input as well as max shift rpm changes. Please note, the new ECU race rom coming out will address 90% of the shitty drivability issues these cars have through custom maps from myself and Racebox—as well as others I am sure.

Increase shift speeds: as seen in the videos I’ve been posting, the TCU shifts much faster once tuned.

Increased shift pressures: as also seen in the videos, much firmer full throttle shifts.
