hahaha, bag removes air, chokes off the engine, making it smoke. bag over intake is same as bag over your exgirlfriends cats head. never good.

No such thing as a smoke switch on a 7.3. That's a 6.0 mod that disables the VGT portion of the turbo.

If you want smoke, the tuners mentioned should get you enough.

You can smoke switch a 7.3...


But if you just want some smoke, dont switch it.
Rig up a 10K mod and that will do better than the smoke switch.
It will cost you 99 cents and take less than 10 minutes to do.

Or if you have the money go with a chip.

How?

Ditto... there is no such thing as a smoke switch for the 7.3...

Well, my buddy with a 99 PSD had a smoke switch, or atleast he said he did...
He tied into a line going to the MAP sensor and when in the off position was supposed to feed more fuel. I could definately be wrong though. I never wanted a "smoke switch"

Think your buddy was pullin your leg.

Most likely. But whatever he had rigged up blew a little more smoke.

got a 99 dodge cummins with an edge with a smoke switch

PSD is right, you can make a smoke switch for a 7.3, three of my friends have done it, i would not recommend doing it at all, one of them blew their injectors, i dont know how though
