^^^ - Welcome! Nothing that I'm aware of for 13+ 5.7's. Been waiting myself for awhile now. There does seem to be some movement from Diablosport recently I believe, as they asked for 13 3.6 and 5.7 examples to work with at their Florida facility recently. I think someone with a 3.6 volunteered but not sure if anyone with a 5.7 has. Where are you located ... ? ;-)

Thanks Rob,
I am located in the Salt Lake City, Utah area. I was hoping to find something that someone has had success with. I just joined Jeep Garage today. I will keep looking. If I find something I will let you know.

Has anyone had any experience with any high performance programmers for a 2013 Grand Cherokee with a 5.7 Hemi?
I have a 2013 and I threw on the Hypertech Interceptor yesterday as a temporary programmer until the Diablo is released. It's an inline "interceptor" with a preloaded tune in the module. Claims +33hp with premium, and my butt dyno says that feels about right. It definitely fixed the throttle lag and added a nice little punch. Throw in the CAI I added and it even sounds pretty good.

No issues with the harness at all. Easy easy install and one added benefit is it's easily removed for servicing by the dealer so they don't know you were messing with things under the hood.

^^^ - IDK, I heard some have had problems with the Interceptor. Think I'll just wait for a Diablosport/hemifever solution.

I sent hemifever tuning an e-mail today and here's what Sean Powell sent back:

"well I'm taking orders for the trinity units. The quicker I can get these in folks' hands and get tunes out there the quicker it'll go :) I do have a 2013 5.7 GC tune that I did a couple of weeks ago, but obviously nobody has been able to install it yet lol"

I have a Labor Day sale going on right now. I've sold quite a few Trinity units (only one compatible with the initial release) so I imagine next week some folks will start having results. But if you want in on the sale, it's going through Monday. The 6 speed transmission folks will still have trans control from what it looks like. If any 8 speeds are out in '13 they may not have anything but engine control

What about the ABS light issue for those that change tire sizes, has Diablo addressed that on the 2013 tunes? Or on the 2011~2012's?? :confused:

I was under the impression it was all fixed. But there's so many different pcm p/n's I will have to see it be successful across the '13 board to know for sure.

What makes you believe the issued was "fixed"?

I have a '12 Summit w/5.7L Hemi and have been waiting to purchase a Trinity w/ some of your very well regarded performance tunes, as well as correcting for the speedometer/odometer error while running my larger than OEM tires.

Do you have anyone who has changed the tire size on a '12 Hemi WK2 running one of your custom tunes without the ABS light issue?

Thanks for your reply.

I haven't gotten a dyno results from the GC 5.7 folks yet. I have plenty from the 5.7 trucks which is the same engine config for the most part. And the '11 and '12 5.7 trucks are showing 30 and 40 hp gains

You wont find a single aftermarket product of
any kind that wont include "some have had problems" to go along with it.

Same for factory products, and the cars themselves

theres more negative reports tied to the diablo tuner than the HT-i for that matter. I think 2 or 3 guys out of hundreds had an HT-i "problem" at the "other" site - I had mine the longest and not a single hiccup ( since last winter)

that said, the HT-I was a great interim solution, made for a nice temporary static performance increase. Now I am ready for a more dynamic and customized experience along with data collection/performance reporting and hard data on what my mods and truck are doing. I'll have my trinity any day now...hoping i can do something with TQ management and tranny (shift points/firmness) among other things not possible with a HT-I

*** hypertech interceptor for sale $200 shipped to all US cities - perfect working condition with both modules & harnesses**** PM's or I can make u an ebay buy-now auction for $220
