P0507 idle speed code with "Tow Tune" '11 RAM 5.7

[johnny248]

So this is strange. I had been running the 87 Performance tune in my '11 RAM 1500 5.7L without any trouble.

A little while ago I installed the Tow Tune. On the first trip out I had code P0507 "idle speed higher than expected" . So I thought maybe it was a fluke. Cleared the code but it returned 2 more times in the same day and one more time the next day .

I went back to the 87 Tune and never saw the code again after 3800 miles. Yesterday I tried the Tow Tune again, and sure enough the code came back twice in the same day. Now I'm back on the 87 Tune and it hasn't come back.

What is going on here?
