Welcome to Just Commodores, a site specifically designed for all people who share the same passion as yourself.
The OBD2 connection is just there to provide power or is it actually sending data over it?
I think the points been missed regardless of the times. The throttle controller is aimed at giving the driver better driveability and better response from the throttle. I think there's dyno figures on the revhigh page. For less than $270 though I don't see why you would even argue. Cheap mod for big enjoyments.
This is what is quoted on the eBay page.
(On a closed drag strip or race track, a side by side comparison using the same vehicle, same driver, but one with a Stealth controller and one without a Stealth controller will result in a quicker time for the vehicle fitted with Stealth controller)
So that's why I was asking for 0-60 times from one of the JC members that actually have this installed.
The fact that your TB will open up 1/1000th of a second faster will result in a faster time, by a 1000th of a second.
If someone sends me their throttle controller I will record both quarter miles and 0-100s in Dash Command for a definitive result, I'm not wasting $270 on it though.
