I have ordered one and waiting for it to arrive. I don't really intend on fitting headers or a full exhaust however have heard of a lot of positive feedback from the tune by itself so looking forward to installing it.

The major thing I enjoy about the RR Racing tune is the 7200 rpm redline in Sport manual mode. Not sure if this is normal, but in 1st-2nd is 6800rpm shift, 2nd-3rd 7000rpm shift and 3rd-4th 7200rpm shift. I did have to get creative installing a used RR Racing tune/device to my 13 GS F-Sport. I'm still getting accustomed to the way the GS drives. I feel the torque converter isn't locking up like the stock tune would during regular driving, but it is overshadowed by the sound of going to 7200rpm.

Still doing testing and trying to gather data to compare to a stock tune.

Another great thing is I don't get a P0430 and P0420 anymore. My cats were stolen 😺....

So me and another Member have been working on getting one from D3 that would be for the 2013. Who is the one you ordered?

I ordered the RR Racing one and had to send it back because my ECU (I am in Australia) is not compatible with their tune unfortunately.

It would be too much effort to source the correct spare ECU to send to them to remap for all of ~10hp at the wheels so I just left it at that.

From what I've read in other posts the tune doesn't do much beyond raising the max rpm. I don[t really care too much about that but would enjoy stronger response in general if the tune can deliver that.

Also it seems like the '13's aren't necessarily compatible with the RR tune. Has anyone been able to successfully install on on a 2013?

Also if anyone has experience with the D3 that sounds interesting too.
