    Speed Limiter Problem 2007 Silverado 5.3 Liter

    Hi,

    Can anyone kindly help me with speed limiter of SILVERADO 2007 5.3 liter. Even before the calibration, this car cas 190 KM SPEED LIMITER although HPTUNERS editor shows 230KM.

    After changing it anything different parameter with calibration, it still cuts off at 190 KM SPEED LIMITER.

    Is there any solution for that????

    Thanks

    make sure you set the "source" to Calibration. If you leave it set to GMLAN it will use the speed limit transmitted from the BCM.
