Anyone notice a VTEC-like bump at 5k rpm? I'm assuming there is a shift in valve timing a that point. I can feel a noticeable bump in power and the exhaust gets a lot louder.

Yeah, I’ve noticed that too. I feel like going to a 245 front/275 rear setup helped a ton with the wheelspin, that and putting on summer tires.
