    I read this on the Cobb website regarding their power gains with their tunes,

    "Peak Gains are measured as the absolute maximum value between the highest points of two plots.
    Max. Gains are measured as the maximum delta percentage between two plots."

    The actual number percentages between the two vary greatly. What does this actually mean with regards to real life driving?
    What can one actually expect?

    Max gains are always better unless you race dyno sheets rather than actual vehicles...

    Peak Gains is the difference between the absolute highest point of the stock dyno sheet and the absolute highest point on the tuned dyno sheet.

    Max gains is the greatest distance between any 2 points at any point along the stock graph and the tuned graph.

    Max gains are the more important number, especially if you look to see where they are in the RPM band. Fox example, a 45% difference at 2000 RPM is much more significant than a 10% difference at 5500 RPM.

    Hope that clears things up for you! We're a COBB dealer and would be happy to go over additional options or answer any questions you may have.

    Thanks for the explanation. So I should be paying more attention to the max gains because this is where I will see the most power put to the wheels at that given RPM? As soon as the 2nd series for the '19's are available I will get in touch.

    Peaks are less important than area under the curve, you need to look at the charts side by side.

    You're welcome! And yes, Max gains are the more important number, however the actual area under the curve and the shape of the curve are the most important numbers to look at. It's best to look at them side-by-side.

    Regarding 2019 support, we have plenty of customers who've purchased the Stage 2 kit and are running the CAI and Intercooler with the Stage 1 ECU Map. You can take advantage of the package pricing now and not have to wait. Then, once Stage 2 ECU support is available, you've already got all the hard parts installed. Just hook up your Accessport tuner to your computer, download the latest firmware, and then load it to your truck!

    Thanks Nick, regarding the package price for the Cobb system, where can I find that on your site for the 2019? I'm not ready just yet, but may be in a couple of weeks. I am also planning on adding an exhaust at some point in the future (havent decided which one yet), does the Cobb tune have to be recalibrated once the new exhaust is added?

    Here's where you can find the COBB parts on our site: https://www.apollo-optics.com/collections/vendors?q=COBB Tuning

    And no sir, you'll be totally fine with the COBB maps and an aftermarket exhaust setup. Feel free to reach out if you have any other questions!
