Hi there,
Those who go to dyno days always get their hardware on the spot. No wait time for such folks. Pretty much bumped to the front of the line. If this wasn't the case, I don't think I would be able to get out of there alive
Hard to say if you'll have your car on time. I suppose I could always bring an extra unit for you regardless. If your car is there, then rock and rock. If not, I could give it to you and you can install it when you get your car. But either way, you would have to sign up for the event just to keep your spot.
cheers
