Does anyone know what mph the engine cuts off the gas flow? My friends bet me I couldn't get it over 100 because they thought it cut off at 98mph but it kept going. Eventually I slowed it down so im not sure when the chip actually goes into effect. 2004 Silverado 5.3L ext. cab LS

the 03s and 04s i believe are set to cut off at like 116...previous years cut off at 98...shouldn't be hard to prove him wrong on this one.
