Hey guys,

I've meant to get a tune on my slightly modded GS 350 F Sport AWD 2018.

Mods: Rims and Apexi Midpipe. I will possibly add intake and axle-back down the line.

I've been waiting for 3+ years for RR racing to come up with a tune. They have not made a tune and keep replying with "We're working on it". My question is, what are the best tune options for this car? I think D3 is best, but I don't have the experience or expertise to know for sure. Can anyone chime in on this?

Jamie @jgscott can probably help answer your question...

Tune options I know of that have had positive reviews are D3, Tune by Loi, and M Force. I have the D3 and love it. The D3 Tune has diffrent options and can be changed by the user for mods added along the way. BTW: I saw some comments a few months ago that RR Racing was actually trying to have D3 do thier tunes for them, but idk for sure?

Thanks for responding this quick. I’ll order the D3 tune likely. Seems to be the best option.

Performance wise that Tune by Loi may well be the fastest of them. But the D3 has more flexibility options you can change yourself.

This is my daily car, the difference in modes sounds nice. But performance is something I’m a bigger fiend for. I looked up the Loi, are they a local shop? I’m on the other side of the country lol.

If you really want to get the power you are going to need a Intake and Axel back. Can you run aftermarket exhaust in NY?

Message Tune by Loi on FB. He will respond. I think he is in the Midwest. All the Tunes and mailed to you for you to load on your ecu.

Does any of these tunes include the TCU tune?

We've had a tune available for 2 months. I'll provide the link below.

Does this open up the ability to install superchargers on -FKS cars?
