Is it worth getting a custom tune?

In my opinion the answer is "yes". I have a '12 R/T with the Road and Track Package and Super Track Pack. I installed the 91-octane Diablo tune (93 octane not available in my area). It was an improvement over the factory tune but the custom tune was even better. I purchased my remote (email) custom tune from HemiFever Tuning. I'm not familiar with Barth Tuning but I suspect the process is much the same. You receive a tune from the tuner, download it to the Diablosport, and install it to the car. You then use the Diablosport to collect data logs while driving the car and then send the log files to the tuner. Tuner analyzes the logs and sends you an update to download and install in the car. You go through this iterative process a couple of times until the tuner sees the car is performing as good as it can with the installed mods; whether it's factory, mild or wild mods.

Thanks for the input. I ended up contacting Jay Greene. I sent him the current file and he sent one back. He told me he changed fueling, timing, airflow, shifting etc - a custom tune with most everything changed. So what I can tell it is a 93 tune refined a bit more than the canned tune from Diablo. So far it seems that it did wake it up a bit more than the canned tune. I did notice that the pedal response is quicker and it does pull hard. He didn't suggest data logging I may contact him about it.

 

After data logging Jay tweaked the tune and I am convinced that even with a stock drivetrain a custom tune will make a difference over the canned 93 tune.

 

Yeh, most factory tunes are calibrated to suit multiple categories of drivers from the young to seniors and across octanes.
So if no hardware mods at least with a good tune your vehicle is calibrated optimally to your personal taste.

There's:

• Canned calibration.
• Calibrate, scan, analyze and address, repeat.
• On Dyno including steady state Volumetric Efficiency calibration, injector calibration, fueling and timing throughout to WOT. The expense for this would better apply better to hardware mods.

I had my stock 2013 R/T but for a Corsa CB and a 180 t-stat dyno tuned seeing the before and after graphs gaining 10H/10TQ.
Sounds small but MOPAR doesn't leave much on the table. I got a better responding pedal, higher shift pints that were firmer and faster, and my air/fuel and timing optimized & calibrated for 93 octane.

The car was made more fun to drive.

 

Boy sounds like the custom tune from Jay works too. What all did he want logged???
