Protune K04
Glad Alex started this thread.
I was K03 with APR, then K03 with Stratified, now K04 with Stratified.
The difference of the APR tune (latest available) to Alex's (the final version of my K03 tune) was the literal meaning of night and day, no joke. Stratified won that, hands down. No fanboyism, just plain truth. My Mk6 K03 Stratified tune beat my Mk6 APR tune and my previous Mk5 APR tune +intake, both in terms of driveability and performance. EDIT: I should add that the APR tunes were not bad at all, they were really good, but I did notice the extra goodies Alex's tune brought along.
Which is why I chose Stratified for my K04 endeavors.
I think the reality is that with the protune you get "individual attention" vs a generic tune. Stratified takes into account every different piece of hardware that you have. My K04 build is really mix and match of components from different vendors. And I do suppose that makes tuning a little more challenging.
Alex, have you tuned any k04s at all yet? I'm curious what sort of numbers you were able to gain.
FriggenT, I can give you info but only via PM. My tune is still a work in progress. If Alex chooses to share info here so be it; it's his thread. I know you're in MD, if you're down by the DC MD burbs at all and want to see how it drives hit me up.
I have exchanged countless (literally) emails with Alex and I'm learning a bunch along the way. He knows his stuff and explains it in detail.
As far as I'm concerned and from my experience with Alex, you can't go wrong with Stratified.
