adjusting throttle cable

I posted this once but got deleted due to board upgrades. My Camaro even with the floor mat removed is only opening the throttle about 95% with the pedal. I didn't see an adjustment on the throttle cable. What can be done to achieve WOT? I mean these TBI need all the flow they can get.

I would just bend the bracket back a little more if that's the problem. If it's the tranny TV cable then you need to move that closer to the TB unit and that might require even more bending.

I'm not doubting you, but how do you know that it's not opening all the way?

Are you having a friend push the pedal to the floor, then are you opening the throttle further with your hands?

Yes I had my wife step on the throttle and I visually was able to see that the blades were not fully open. I then used my hand and was easily able to open to WOT. I hooked my laptop up to the diagnostic port and stepping on the throttle yields 4.02 volts on the TPS sensor and if I open it by hand I can get 4.5 volts. I haven't had a chance to bend the bracket like Jon suggested since I have been working on my dads Christmas present.
