I just grabbed the gold using the 92 F40 with the linked specs above. After about 30 minutes I gave up on the GTR Black with the linked tune specs because I couldn't manage to get over 4K. Once I made the switch to the F40 I had a bunch in the low 4K's. Finally, I just locked in a solid drift around the full big bend, then swung it in home for a casual 4880. Right away this car and setup just clicked for me and felt good. I'm on a controller and drifting isn't as smooth as with a wheel, pedals and sifter I think.
