Dyno-Verified Power Gains

Expected Stage 2 gains on 93 octane: up to ~295 HP / ~330 TQ. Results vary with dyno type, altitude, heat-soak, fuel quality, and hardware condition.

ECU Tune Modification Requirements

Stage 2 hardware (quick view): Stage 2 is a downpipe-required calibration. Intake and intercooler upgrades are strongly recommended for consistency and heat control. A TCU/DSG tune is highly recommended where equipped.

Crackle Pops (Overrun)

Subtle on stock exhaust; aggressive on freer-flowing setups. Tuned with RPM windows and exhaust-temp safeties.

Boost Control & Drivability

From the factory, boost delivery can feel uneven on long pulls. BDT refines the curve for linear onset, faster response, and smooth, repeatable power without surge.

Software Install Requirements

WINDOWS LAPTOP REQUIRED (NO APPLE)

IF YOU WANT YOUR CAR TO SURVIVE, THESE MUST BE DONE!

I WANT YOUR CAR TO SURVIVE MULTIPLE YEARS TO COME WITH MY TUNE. I DON'T RECOMMEND THESE FOR FUN. I HAVE TUNED COUNTLESS EA888 CARS AND THIS IS WHAT I'VE SEEN THROUGH THE YEARS. IF YOU CAN'T AFFORD THE PARTS, PLEASE DON'T TUNE YOUR CAR. BEING STRAIGHT FORWARD SO YOU DON'T BLAME MY TUNE.

Late Policy: If you book an in-person flash and arrive late without notice, a $50 fee applies. Reschedules must be made at least 1 hour prior.
