For those of you that have got a chance to read my newbie post, I am on the highway a lot for work. My 2011 Nitro Heat R/T 4x4, with the 4.0 does decent on gas and has decent power. But as like anything else in Merica, more is better. I was browsing the threads and swear I seen somebody that has a turbo on there 4.0, but now I can't find it. What are some general mods to consider for waking up this sleepy beast?
