I would say mine is also about 5, maybe 10 degress away from being at 90* when at WOT.

With my Nick Williams TB I had to make a new cable bracket to get the TB blade to work right. After that i have perfect TPS. Then again I have an '01 setup and not the DBW.

I first checked my stock setup with my HPT scanner connected.
stock the TB goes all the way open 90* at 100% TPS indicated just before the throttle pedal is all the way down.
Next I checked the 90mm stuff, it will only open 75% of the way,
the scanner shows that the throttle is at 100% when the throttle pedal is only at 75% if you push the throttle more nothing changes still indicates 100%
and the TB is still only 75% open, I think this is a problem and my be why some are not seeing the expected gains from this mod.
attached is a pic of my stock tb at WOT and a pic of the 90mm at WOT.
BTW this is on my 2005 GMC truck in the sig.
