I have a 2008 Ford F-350 Superduty with the 5.4 v8 in it. I was wondering what I can do to get more hp out of it? I Am new to this whole thing. Iv looked over turbos which there really isn't anything I can afford.i have a K&N air intake and looking into a tuner from 5star, I also did a muffler swap. I'm just looking for somthing to beef up my engine! Thanks guys!
