Throttle Body - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

I have a Nick Williams Boosted 102mm on its way. However I have a regular NW 102mm and when I am reading it off my gauge and I smash the pedal to the floor it reads at 85%.
I know this is a noob question but isn't WOT considered at 100% ?

So in addition to that question what is the usual Throttle Percentage when it's at idle or at WOT ?

I see mine at idle between 11- 18%
WOT between 79-85%
Could the TB be at it's last legs and needs to be fixed ?

Thanks in advance

I'm sure your throttle blade is 100% open at 84% TPS

Yes, 19 or so at idle, 84 at WOT is normal. Log the SAE pid to get 0-100 if you want it.
