no watermark with custom tunes?

Hello. I see that the intune is warranty safe according to the site. What about a custom tune? Does the device make no watermark or does it depend how a tune written? The place I was looking at was hemifever tuning and they are apparently tailored/modded canned tunes. 14 5.7L ram btw.

we always write a watermark, thats nothing the dealer can see, the process is the same whether custom or canned tunes are used.

Thanks

Also if I order an intune from here, how many tunes come with it and is it certain ones or do I get to choose which tunes come with it? I had an Sct tuner for my ford and it let me select any 3 out of like 16 tunes available. Just wondering what options I have. Also i am at 5500+ ft and read on another thread that you recommend using the same octane or higher as the tune number. For example 89 tune can use 89+ even tho elevation changes things a bit. Also what parameters are adjustable? I need Rev limiter, speed limiter, more power of course, and speedo correction. Also with my f150 I bad to set the rotations per mile during the tune even tho they were stock. Am I going to have to figure that out or is that something that transfers over on its own? Thank you.
