Will this work, egr delete with no tunes...

If I install an EGR delete kit, like from Sinister Diesel, and leave the valve in the intake manifold and plugged in, will I still need a custom tune?

You can do the delete but might get a check engine light.

Even with the valve in the manifold and plugged in? The way I understand it if I set it up like I said the truck shouldn't "see" that there's a delete there since the valve is in place and connected. So I'm only guessing there will be no codes and I'll still have the benefit of eliminating that recirculated garbage in my intake.

05-07 knows when there is flow and how much there should be from the egr, if it has no flow, as the case will be with your truck, it will throw a egr low flow code. i would recommend custom tuning and roll with it

Ok so I just bought an 06 and it does have the sinister egr delete kit installed. There is no tuner on the truck and it is throwing a code. The previous owner has a code reader and he would just erase the code everytime it popped up. Is it ok to keep driving it with the code thrown. Is it necessary to get the tuner so I can delete the code? I am wondering if it will drive better or the same with the code thrown or not.

Well, here is my input on that...Having the code isn't really gonna cause any problems for you. However, when there is a problem, that would generally trip that check engine light, you aren't gonna know unless your checking for additional codes on a regular basis.

Just a thought.

I have a canadian spec truck, 2005 late model and have deleted the EGR cooler and have normal operating features and no codes. The only thing that changed is that there is higher exhaust presures when cold due to vanes on the turbo closing to create faster warmup and a lack of power after cold startup until warmed engine. By shutting down the EGR Cooler the heated EGR flow is now blocked and the exhaust has to make its way through the turbo.
I have discovered that the EGR flow is also diverted by the turbo vane controls, that shuts turbo flow and increasing the Exhaust gas pressure that I can measure with my ScangaugeII.
