sorry about ANOTHER thread guys but im very interested in the 08 intake manifold swap onto a 03 Dakota 4.7...first off my biggest question and the most important would I absolutely HAVE to get a custom tuner or could I just stick with the superchips?(it says on airram that some ho cams, a 70mm tb and that intake manifold are a great combo)...because I literally just but the superchips like a month ago and love it! also I REALLY don't have the money or time to go get it tuned on the dyno...next what kind of horsepower could I expect? and lastly how tough would it be for me to install? thanks guys and sorry about another thread lol
