Did the pulleys today! Definitely feels super sharp and crisp in the acceleration department.
Also did a full oil change. Dumped Motul 300V in the engine, 300 in the trans, and 300LS in the diff; pulled out an odd amount of shavings in the diff; but I'm not too concerned.
When it was done, the guys at Fuzion Teknique recommend I try RS-R's new Ran UP stuff; it's a nano ceramic oil treatment that supposedly boosts horsepower and torque efficiency while giving better oil life. It sounded like snake oil, but I gave it a shot and decided to be a guinea pig for them. Put it in the oil chamber, didn't feel much, and drove off. Probably 30 minutes later I notice a smoother idle, quieter engine, and generally a more "peppy" feeling to the motor when not actually accelerating. Not bad, but I'll definitely need to try it more before I decide to do it again with an oil change further down the road.
In addition, I noticed one of my gaskets were literally falling apart. Pulled out to discover this. Guess the seal wasn't perfect when I transferred my exhaust over from my 10 Series; thankfully I was able to replace it with a GrimmSpeed gasket.
