I agree with the others. I'm not a big believer in dyno tunes. It's a false environment that doesn't actually translate to the real world. An email tune based off of logs is more likely to perform better, and match your driving style and location.
I also think the mod level is somewhat irrelevant. When my Jeep had simple bolt-ons, I did an email tune. As the mods and power doubled, I stuck with an email tune. We threw it on the dyno several times, but just as a starting point, and bragging rights.
Now that I'm doubling the power again, it'll still have a log based tune. However I'm more interested in drag racing, so my logs are only based on passes I make at the track. That's what I want it optimized for. At a certain power level you gotta ask yourself, how much tweaking do I really need to go get groceries or merge onto the freeway? Most won't be at full throttle or doing launches all day long. So consider intended usage when recording logs.
The trannies are much more durable than you might think. Even with way more power than it was designed for, a custom TCM, and abusing it every week at the track, my OEM tranny lasted almost 300 passes. Less abuse would last even longer. With the Ram it was more a matter of feeling like it had a real tranny and not a CVT. Now it jumps when I get in the throttle a little and it shifts. But I don't do that all the time. So a little less torque management is a good thing IMO, and won't shorten its life. Same with the mods and tuning. It's my pickup truck, not my race vehicle. So some bolt-ons and a good tune makes it feel peppy enough to keep me happy, for now. And anecdotally, I did take it to the track to see what it would do. I beat an F-150 Ecoboost, and a Mustang GT, twice.
Again, usage dictates mods, logs, and tuning.
JD, a canned tune is one that is included in a tuning device, like a Diablosport device. They are written with a CYA for the vendor, not utmost performance. That's where a custom email tune based on logging certain parameters comes into play.
Hope that helps!
