mine has always been tuned after it was blocked off. i blocked it off first because i couldnt get a egr pipe to not leak. plus it was just a PITA to work around
Yeah I am now having that problem mostly all the time. I did hundreds of uim removals in the past just fine but lately it's been the same as you. Leak city . How do you turn it off in the tuning, you delete the dpfe sensor from the parameter list?
from everything i read the full 3l always needs a tune and no matter what motor the egr delete would definately need to be turned off. i played around with scts stuff in the past but dont have pro racer or anything so i only have a general understanding of it. it seems like it could be as simple as unchecking that parameter. i have a port matched untuned as well but i am always tweaking and changing hardware. when my delte kit comes in maybe ill try it and see what happens without the tune.
