There's no more or less tunable parameters across the many devices.
What tunes did u go with?
I just installed the MPD budget 64.5 sxe on my 13. Overall I'm happy with the performance. The only complaint I have is that it is quite a bit laggy city driving it. I haven't installed a piping kit yet which I'm told will help out a bunch. I'm running tyrant tunes that have been redone for the non vgt set up. I'm really wanting to do fuel next.
