Im going to be ordering the sct from eric with custom tunes. I have a rcd egr delete kit also on order. My quesion is with the tunes be different if I don't get the egr deleted by the time my tuner get here. Should I wait and install the egr delete then order the tuner? Sorry if its a dumb question. Other thing I was thinkin about doing is an oil bypass system. I have read many great writes up on here about them. Is it still worth putting the bypass on the truck once the egr is deleted?Thanks for the advice in advance guys.
