driving withVGT off bad?

Anyone know if running the truck with the VGT switch off (smoke switch) is a bad idea if your not beating on it? seems the truck runs like an old 7.3 with the switch off... which i dont mind, but is it bad to run it like this? pro's cons??

I havent done it long.. i kill it every now and then just curious if i shouldn't be doing it.

For those that don't know the VGT is hooked to a toggle switch so my turbo vanes stay at the maximum size possible for the turbo... think its a 60mm?

Gonna make a mess of your vanes and unison ring.
Then you'll have to pull it very quickly and clean it often.

ok, was just curious.. truck actually runs pretty clean when its shut off... last time i tried i couldn't get much black smoke out of it even powerbraking with VGT shut off. Running a S&B intake, 4inch DP to 5 inches straight pipe.. SCT tuner set on extreme performance... so thought it was weird i cant smoke it... any thoughts?

IF you have have a cat converter this is a great way to plug it up. I would never do this on a truck with a DPF. Doing this on the road gives diesels a bad name. With all the tree huggers out there, this is not the example we should show. We should be showing the clean , Hi Performance side. This also makes your truck look like a POS and the driver look like a real D-bag... Looks cool at the track or mud run, so lets keep it were it's welcome






Yes before You flame on me, I know 6.0's don't have a DPF

Are you sure you did your "smoke switch" correct?
