This exhaust crackle is completely safe and entirely addicting. Optional feature included with stage 2 and K04 tunes only.

Your new high-performance tune is calibrated to safely maximize the engine and turbocharger power capability without sacrificing reliability or daily comfort.

Every ECU parameter undergoes months of testing on our in-house dyno systems that utilize the world's only Sea Level Generator developed specifically to verify safety operations in any condition. Confidently drive from LA to Pikes Peak with power that will keep you smiling every mile!
