  I'm not a speed person but I like to know my truck is in top shape
  Odo reads 99073 on the i way I tried pushing it to a 100 mph but it not go can anybody tell me what's happening to my truck

  Well, after almost 100K the engine is probably not putting out as much HP as it did when new.
  
  And, the frontal area of the Tundra probably limits the top speed as well.
  
  Not exactly sure why you need to know how fast it will go, when the highest speed limit in the country is 85MPH on one stretch of road in Texas.

  I believe the top speed on your truck is limited by the ECM--something like 105 mph, in order to conform to the tire speed rating. So with speedometer error, I'd say your truck is being stopped by the computer from going any faster. Probably even without a limiter you couldn't go all that much faster, given the gearing and the aero effects. You really wouldn't want to, as the truck might "lift" at such speeds and compromise steering. It's really not designed for high speed.
