Hey Mn, thanks for the update, I always appreciate the nice comments.
You're not supposed to be using that feature, shifting into overdrive at 5500rpms, LOL.
Glad you're enjoying the tune and keep us updated on the header install, I bet that helps out quite a bit. btw, Brian is top notch service!
thanks,
allen
