Hey guys.
2014 6.7 efi tow tune and trans tune 68RFE. Full delete. 5 tb.
i had a trans tune written so my tow tune had to be reflashed. After the reflash I seem to have picked up an engine tap or knock at idle. This is after engine is warm. Runs great, no smoke and good mileage. Is this something to be concerned about?
thanks in advance.
