it isnt labeld as a "smoke switch" but there are alot of people that sell the part... boost fooler... all the smoke switch is a cheap version of it.. simply tap into the map sensor with a togle switch and your done.
there are different color wires for different years and you need a resister so you wont get a CEL or defuel (lug mode)

 

you have to have a boost fooler for it to work as well. i did mine, you could tell it would lug it out. very little smoke. definately not worth what you can end up ruining. id suggest just stay away from it.

 

boost fooler isnt that good of a idea unless you have built the block to hold the high amount of boost... normal operating pressure on my truck is 105 kpa (15.22 psi) with the boost fooler i went to 149 kpa (21.67 psi) and with the switch i get 255 kpa (36.98 psi) i havent tried it with a boost fooler and the switch but i imagine it would give 40 psi or more.. that is not good news for a stock turbo...

 

that kind of boost pressure is weak for the newer coomon rail trucks my truck pushes around 33 psi bone stock and about 42 psi with my edge turned up, ihave heard that the newer common rails will hold right at 50 psi without many worries.

 

yeah 50 psi is what they'll hold, but i don't suggest taking a stock turbo to that level, that's just nuts 45psi will spike the turbo and much time at 50 will surely fry it

 

on the 07 5.9 i killed a turbo at 52 psi it snapped the shaft and wiped out a housing
