EGR Valve in place with EGR Cooler Delete

All,

I should be getting my truck back tomorrow after arp studs, gaskets, etc...

EGR Cooler was deleted, new up pipe, etc..., however the EGR valve will remain in place.

Does anyone know if the EGR will still operate? Open or Close? I know that the exhaust won't be coming back into the motor, just curious about this.

I plan on running tunes with my SCT but wonder if I run stock or a tune with EGR Valve enabled if there will be any issues?

Thanks!

-Evan

I run the sinister EGR delete kit, valve in place plugged in and a edge juice plat, and have no engine light or issues. No codes even. Runs great. I had the chip before I did the delete, and now it runs better. I dont think you will have any issues.

I dunno The performance shop didn't specify which brand. The EGR cooler will be completely removed and a new up pipe will replace the stock one.

The only issue you could potentailly see is an egr flow code. on later calib. PCM looks for a temp difference between IAT(in the MAF) and IAT2, (in the intake) you will probably see this on your 05 with stock tuning

I left the valve in to prevent codes. I have a early 04 so I dont get a light anyway, but this way the computer seems to think everything is OK. Dosen't hinder performance so I am happy.

I guess I'll know for sure tomorrow when I pick her up and drive home on the stock file. Good news is I will be flashing to one of my custom files with EGR valve turned off.

Also, my 05 doesn't have a MAF, so I may be good to go

Your check engine light doesnt turn on but I believe your truck still throws a soft code...just FYI

my egr valve is still in place, but is welded shut. I was getting a code for the valve but had my tuner write in my sct tune to get rid of the code.
