I purchased my 2014 R/T Max about a month ago. Coming from a 2008 Chevy Impala SS. The very first mod I decided on was the Intune + custom tuning. This combination turned my sedate Impala into an actual performance sedan...in a straight line anyway .
Purchased the Intune from Amazon as they had a decent price and got it to me in 2 days with my Prime free shipping.
The update / install process is LONG with this car. Prepare to spend a couple hours between updating the tool and going through the long PCM backup process on your charger.
The canned tunes are just alright at best. In my opinion the canned tunes alone aren't worth the price of the tool. The value comes in to play when you get someone who knows what they're doing to tune it for you. I applied the "Diablo" tune designed for 91 octane, boosted the throttle to 15% and killed MDS because MDS + Diablo tune don't play well together. There was a difference in throttle response and a little more pull, but it was tiny.
I contacted my GM tuner to see who he recommended for Mopar and he shot me Johan's contact info. Got in touch with Johan, requested a 93 octane tune without MDS and with firmer shifts. Paid for the tune in the middle of the night and BAM had a custom tune waiting in my inbox when I woke up the next morning.
Applied the custom tune to the car and the results were just like with the SS. The best way to describe it is it feels like the car just "woke up". Drastically better throttle response and noticeably more power. For a car with no mods it was worth every penny of the cost of the device + the tune. Once I get a CAI in place and a good catback exhaust I'm sure it'll be even better.
Gas mileage....well. With cruise on at 65 on the highway I was getting around 24-24.6 on BP 89 gas with no changes in speed on flat roads with the stock tune with MDS. Repeating the same test with the tune I got around 24.8 with BP 93, same stretch of I-20 in South Carolina. Problem is the throttle is just too tempting now . There's no such thing as a gentle pass or gentle start. If I could keep my right foot out of it I'd say the mileage is on par with the stock tune, but I didn't tune it to keep my right foot out of it.
Still working with Johan doing some datalogging to get the tune exactly right. It gets just a tiny bit better each time he tweaks it. Support and response have been great. Johan comes well recommended from a buddy of mine from the GM world so I have no problem at all repping him for Mopar.
Be happy to answer any questions about the process or results.
BTW - my first review / post, so be gentle :driving:
