Will the egr valve still try to cycle after its thrown P1335 code

I swapped to the 210 TCM enhanced tune and threw the P1335 code again. I think its been stuck for a long time as I dd with the 310. After it throws the code will it still try to cycle? Im wanting to keep running it to see if it will free up instead of having to take it into Ford.

You need to load a 175 or lower hp tune. With the 210 tune the valve will only try to cycle at idle. With the lower hp tunes it will open and close just like a stock file. After you load it then go out and run the crap out of it to see if it will free up the valve.

Thanks Mick. I loaded the 175 and flogged it. It seems to be working some, sometimes it goes to 100% then other times it still reads 0. Now I've got code P0404
