Congrats on getting boosted!

I don't have all the details yet, but apparently my car will be the first 392 in the area w/o needing a harness swap. We will be sending the ECU up the road to Arrington and I'm told that a solution is in hand and will be available shortly after the turn of the year, will post more details as I have them!

My understanding is that Arrington has been given the ability by Chrysler to access the ECUs.......

Ok I have the 411 on that one. You will be getting the MOPAR tune which will be a detuned version of the current Arrington tune that is on their ECU swaps to meet MOPAR specs. That should keep all your warranty intact with no questions asked.

True statement they are using the same guy (Dave Kasper) that I used to bring out the ECU swap and still use to provide a complete tune for Diablo owners since Diablo CMR software is currently short on tuning capabilities.

And currently Diablo can't tune 2013's so I have the only solution for them until MOPAR comes out with their ECU swap which will be a watered down version of what I offer today.

So what kind of power should I expect out of this detuned version of Arrington's tune? I was told to expect about 560-570rwhp......

Congrats. You are in fine hands with Arrington.

I'm just going by what Arrington told me when I got the quote for supercharging, he said good to go with the autos, its the manuals that have the problems. I've been told this several times, after making sure to ask. ..of course this was with only 540RWHP and street tires. Different story with slicks. By the way, what exactly is "limp mode"?

A dead transmission. OP You might want some wider tires to go with the supercharger too, although we really can't go that wide on these rims unfortunately.

Great advice, I'm actually working on that now, I'm trying to find a decent set of aftermarket wheels without breaking bank as I just bought a set of 3 piece ADV wheels for my BMW M5. I was thinking of some Vossen's for the challenger which seem fairly reasonable in price. I definitely want to go at least 295 series tire, but the max width you can go on the stock rim in the rear is 275.
