Yeah, I'm not too great of a tinkerer, but thank you for throwing it out there as a possibility.

JR, thanks for clarifying the VVT situation. I'm still surprised at how low you go with 5th, as I've expressed before. Perhaps your better aero (topper) takes some of the required throttle position out of the equation, but if you're geared the same as me (3.73) with the stock tires, then we have matching engine speeds.

My engine can do 45 mph in 5th comfortably at 1500 rpm. Any lower and a mild low vibration tells me urges me to downshift. Oddly, the shift-indicator light does occasionally pop on at 40 mph, when I'm on flat ground and babying the throttle.

I've heard of tunes helping some guys out in this department.
