I’m looking to upgrade from ie stage 2 to their new k04 tune. I’m still putting my kit together (rebuilt s3 k04) and wanted to hear some input from those who’s cars are actually running on this software. Leaning more towards upgrading for $150 dollars than getting a custom tune. The power claims are kinda nuts so I’m interested in that.
