i would go ahead and get a tune cause it will run rich idling and at slow speeds but at WOT it will run lean. i have the lt4 hot cam also.

I had a pcmforless tune in my car for over 2 years with the Hotcam, then got another tune from madz28 when I swapped cams. can't go wrong with either of them.

Personally, I would get the headers before I got the hotcam. If you put the cam in before you put the full exhaust on, then you wont see a whole lot of gain.

As far as 8mpg...Im not so sure about that, My cam isnt much bigger than the hc, and its not tuned, and I get 23mpg...no seriously! The only reason mine isnt tuned yet is because I am going to do a gear swap before the summer is out and I dont want to spend the money twice for a tune.
