hi is there any way to make a smoke switch on a 2005 duramax

Customer Question

hi is there any way to make a smoke switch on a 2005 duramax lly, will it hurt my engine or anyhting in any way, i tried putting a toggle switch on the 5v refrence wire from the map sensor and the out wire on the map also tried taking the yellow wire from the maf and tapping it into the green out wire of the map sensor, it did work i had tons of smoke come out of my stacks when i put the switch on, but when i turned the switch off the truck barely had any power at all, so i disconnected the yellow wire and evrything went back to normal. im thinking there is no way to make this work.

Eric :

Hi. I agree that it probably won't work well, for what you are trying to do. Have you considered just getting a tuner for the truck?

JACUSTOMER-ka41dqk9- :

yea i have a ppe tunner but it only smokes on level 5, what sucks is the tranny wont take it on that level and i have no pyro gauge to know what my temps will be at

Expert:  EricFromCT replied 4 years ago.
Oh, ok. Are you interested in installing a pyro meter?

yea that reads egt's right i was gonna instal one in the manifold or down pipe to rear combustion chamber exhaust temps

Expert:  EricFromCT replied 4 years ago.
Yes that is correct. The pyro is a good idea because the exhaust temps will definably rise when dumping more fuel in.
