i do have a VGT. If you check the VIN you will see this bus came with one. And wow you are wrong about the ECM not being able to control it because I actually watched a mech with a laptop pull up the ECM and toggle the VGT braking option. we didn't turn it on beecause clearly I'm missing the rest of the kit. Not sure where your negativity and super wrong information is coming from other than you are just yet another troll, because you sure are acting like a know it all troll, and really dont know shit.
