Somewhere down that cable should be an adjustment clip. Is the TB actually opening up all the way and saying at 100% open its 85% or is the TB itself not opening all the way when floored?

The TPS and throttle body are in sync at 85%. I can manually get the other 15% by hand so the throttle body WILL open all the way, just not with the cable. Even though the pedal is to the floor

Phantom Black Metallic- 2004 GTO M6
I'm wondering if that cable is stretched, or if it is supposed to be like that to prevent early redline? Never heard of any issue like this before.

Does anyone have a diagram or can tell me exactly where this adjustment could be? I took the the coupler apart in the middle of the cable and only saw the spring that looks like it keeps tension on the cable housing, nothing that looked like an adjustment. Thanks guys.

You might have to bend the gas pedal up to get WOT.

Custom Swirly Black- 2001 WS6 M6
I think it's suppose to be like that. And I think the % is actually * (degree for an angle). Think that's why the bump stop mod exists, as most of us are 80-85, never coming 90* WOT from the factory.

That's what I am getting at though is that there is a 1/4" space between the stop screw and the throttle body stop with the pedal all the way to the floor. So shortening the stop (although maybe needed at some point) would not solve this problem. And I did take apart the cruise control box to see if there was room for improvment from the pedal to it and there is not. Foot to the floor rotates the cam in the cruise control box all the way, it just doesn't pull the cable that runs to the throttle body open anymore. So issue is not with gas pedal. Just to clarify software we are using is HP tuners to see this.
Thank you for the link to the mod as it did help me understand how the LS throttle system works better. But we are not getting anywhere close to that stop at this point.Last edited by texas97z; 09-24-2011 at 10:44 AM.

1999 Formula WS6 M6-sold- 2001 Silverado Z71
Here's what the adjuster look like.
I think you want to make the cable sleeve longer. That has the effect of making the cable itself tighter/shorter.
The other variables here are that there are 2 different throttle bodies and 2 different cable lengths to go along with those TBs. If for some reason a incorrect year TB or throttle cable is on the car, you may never get it adjusted all the way correctly. Any chance he has a 98-99 TB on his car?
