HemiFever tuning

Hey y'all was considering custom tuning was wondering from y'all that have it what kinda difference did y'all feel from it?

You cant go wrong with Hemifever. He has tuned enough of these trucks that it is just second nature to him now. With your future heads/cam upgrades coming, I would talk to him first to see what kind of package he can put together for you. This way you aren't paying for basic tuning right now and then having to go back for more specific tuning after the heads/cam install.

In all honesty, with your current performance mods in your sig, you may feel a slight gain over the canned dsp tunes but it wont be much. It wont be an instant transformation into a race car or give you boat loads of more hp/tq. If anything it will make it run a little nicer/smoother.

Personally, with your list of mods, I would pass on the custom tune for now and pick up a wideband o2 and get that installed first. You need it for any custom tuning specially when it comes to cams/heads. After that, get your parts decided on for your cam/heads, and then I would focus on the custom tuning of it.


Edit.... Just saw you had headers installed in your other post, still would get a wideband before custom tuning, and still would probably hold off until you get a cam and/or heads. I had a custom tune from him after I had me headers installed because I was getting a lot of KR. The performance really did not go up any, just the driveability smoothed out a bit and the KR was reduced.







































(also........ make sure you get a PCM AND TCM custom tune. The PCM tune will make it run smooth, the TCM tune will turn it into a hot rod.....)

I had a CAI and muffler when I got the HF tune, the difference is there, much better feeling acceleration, better shifts. Definitely better over the canned tunes. Like truckin said, it's not an instant transformation, but it's definitely worth the purchase.
