No worries. I don't have the NITTO tires, but I've been having the same action due to switching to Pro Comp ATs. I could get the TOD meter to fully light up under hard acceleration on dry pavement even with the stock tires, and now it flickers every time I start to accelerate. The TOD system is adjusting for slipage as it's supposed to. I like watching the guage flicker like that... a reminder (as if I need one) of how wicked cool the VX is. Good times!
