Im racing this weekend and didnt even think about speedcut. Is there anyway to bypass it without running an SLD? Id like to save the $100 for this weekend if possible.

Does it really matter? I will be going over 120 I am sure. Thats the point.
But I will be drag racing.

Zazzn, any instructions on this zener diode hook up. So you can do that for boost cut and speed cut then? I saw this option for boost cut before, but I can hit 2 bar fine, so I should be good there

If you really need a quick quick fix just unhook your speedo cable from under the car and you wont have speed cut anymore.... you wont have a speedo reading either, but who cares about that.

If you are dragging, the only thing you should be looking at is the roadway and the tach.

Just don't forget to reconnect it!

no it's the wire you don't need to unhook the mechanical speedo cable.

just the wire to the ecu.

Most definately not. At least not here in the good 'ol U S of A. I've been at 140+ on a number of occasions, and unless the speed cut is over 150, which would be stupid, then there isn't one.
