I unplugged my EGR on my truck today, and when I first start the truck it almost stalls, among other strange actions.. But once out on the road I do notice a 1~2 mpg increase, louder turbo whistle and it no longer blows black smoke. With the actual blocker kits, do the trucks have the negative side effects I explained?

 

from what ive been told if you just unplug your EGR valve it will make your truck go into limp mode if you want to do way with your EGR valve you need blocker plates and leave your EGR motor plugged into your harness but disconnect the motor from the EGR valve thats how mine is and ive had no problems...i see smarty has instructions on how they do theirs also

 

I've been running my EGR unplugged for over 20,000 kms. What I would do is disconnect the battery negative cables for about 20 minutes. That should reset the computer and allow it to learn without the EGR. Your engine light will be on constantly, as well. I am presently testing a Boost Fooler on my truck. With the EGR plugged in the Fooler makes the computer throw the EGR code and turn on the engine light. I am presently running the Fooler with the EGR unplugged. Throttle response has improved and turbo spool up time has been reduced.

 

I think it also depends on the state of the software when you shut the truck off and unpluged the EGR.
There is a butterfly gate at the intake, if that was half closed, then you will have issues. Or if not, when you start it, it closes mostly.
That is the reason I took that gate out in order to drive it with EGR electrical connection unplugged.

 

Is it natural for the truck to blow less black smoke when your egr is unplugged?

 

Where is this "butterfly gate at the intake"? What I am planning on doing is, keeping the EGR plugged in, blocking off the hose from the exhaust to the EGR and removing the intake butterfly, if I can find it. My thinking is that the cel will stay off, no codes, and with the butterfly removed it won't try to close and choke off the air supply. Anyone try this yet? What do you think?

 

That's what people are selling as an EGR delete kit. It's a washer on the exhaust end of that EGR pipe and plates to remove and block off the valve on the air horn. The round silver cylinder connected to the air horn is the butterfly gate. There are two screws holding the plate to the actuator shaft. I have not been able to remove the plate without breaking the screws. So, I just drilled them out.

 

Thanks caveman. I'm going after it this weekend and also try the resistors in my dpf pressure sensor. My dpf delete is throwing a lot of codes.

 

I have a 330 resistor for the pressure sensors on a truck very much like my daily driver. No codes after almost a week with the Smarty. I heard you don't need the resistor now with the Smarty, but have not yet tested without a resistor. I will in 2 weeks.
