I too would love to see that but I emailed Sean about that a few weeks ago, he indicated that Diablosport has to come up with support first. I'm thinking it will be a long time.

Welcome Sean!

I've got a 2012 Export hemi (Australia). I am itching to get a hemifever tune after hearing so many good recommendations on JG about your tunes, can you confirm if the diablo sport can tune export models?

they generally do export stuff way after initial releases. But get your pcm p/n and call Diablo and ask if that p/n is supported or not.

Silly question - where do I find the pcm p/n?

Thanks very much.

it's on a sticker on the pcm itself. I've seen lots of folks overseas with US based pcm p/n's so thought it would be worth checking just in case

Re: Hemifever can now tune 2011 5.7 GC's

Hemifever I believe is the best possible tune for the 2011-2012 Jeep GC 5.7L Hemi

Re: Hemifever can now tune 2011 5.7 GC's

I have a silly question, how do you install these types of tunes? I've seen a lot of positive feedback on the hemifever so I'm thinking on pulling the trigger, but I'm not sure what I need or how to install this. Do I need to purchase any other upgrades...exhaust, intake etc.? I'm just a normal guy and not someone who works on cars.

I'm most interested in improving the sluggish trany shifts.

Re: Hemifever can now tune 2011 5.7 GC's

First you'd buy the intune-dcx or the trinity. The intune-dcx is cheaper. Both tune the same, but the trinity has a few gtech features like a 0 to 60 timer and 1/4 mile timer.

I send the tuner with Diablo tunes on it. with the intune-dcx tuner, you'll update it and install a preloaded tune. Connect the tuner to ur pc with the supplied cable. Open up email and attach the "last tune written" from the intune drive. I'll edit it and email it back with my settings.

Re: Hemifever can now tune 2011 5.7 GC's

It's probably the easiest install you will ever do on the jeep. I bought my unit from Sean at hemifever.com. It comes with a hand held device either the intune or trinity whichever route you choose to take, and all the necessary cables (OBD2, USB). It's a simple plug and play and it flashes your PCM. You can upload new custom tunes to the device via your computer and supplied USB cord. Here is a quick video I found on YouTube that will give you the run down. It's a jeep wrangler but you get the idea.

Re: Hemifever can now tune 2011 5.7 GC's

Thanks for the feedback. The $599 option includes the diablo device, correct? I would just do that rather than buying separately. How do these work with the select terrain modes? Normal vs sport vs snow

Sean's tune for my 2012 Hemi was for both Sport and Normal. The other settings are not effected.
