I have a 8mr and im having the p0401 code and rough idle. What all is needed to delete the EGR?

 

Block off plate and disable the code

^ and thats the complete way living in Cali we have to leave all that stuff on for the visual effect that being said I took all mine off anyways!

 

So do i HAVE to disable it in ecu or can i just put the BOP on and deal with the code until i get a tune and disable it then?

 

does removing the EGR makes a big difference???

 

From what I have personaly seen its around 8whp +/- 2. if ur hunting for everying pony then i think its worth it, but keep in mind u will be doing this at the cost of mpg and the car would usualy take a bit longer to warm up (maybe an additional 4 mins or so).
