Hi guys,

I took out my intake and had the TB in open view, then I put the car to the ON position and had my brother depress the accelerator pedal in different ways (quick full throttle, slow full throttle, etc..)

People have said that the valve only opens to 60 or 80%, but it actually opened ALL the way.

Something else I notice was sometimes when his foot was already on the floor the valve was lagging and was slowwwwly opening at small increments, why is that?

So to those who think that toyota is keeping is tuned down, you are very wrong! the valve does indeed open all they way up!

 

probably because its not a cable throttle body like most cars. just an idea..

 

ehh not really the answer i was looking for, it doesnt normally go up in steps when the car is running... why did it to that when i was looking at is??

was it cause maf was disconnected?
