change oil before dyno tune?
Track dedicated/high HP motors are usually built a little looser and can be thrashed on right out of the box.
Lots of folks will make pulls immediately, others will try to give the motor some break in time. Matter of preference I suppose. Will it "hurt" it? Prolly not if everything is in order. Got good oil pressure?
The old saying "Break it in like you drive it" comes to mind......
