Hey guys,

I am currently running EFI Live with PPEI tunes. I have considered switching to an MM3 tuner and running DRD tunes.

Can anyone give me some pros and cons in regards to this?

I'm trying to do as much research as i can and get some experienced opinions since it's not a cheap decision.

Also, in regards to the 12V tunes, does that change the tone of the exhaust?

Some specifics on that tune would be greatly appreciated as well!
