Dyno-Verified Power Gains (AWHD)

Expected Stage 2 gains on 93 octane: up to ~335 HP / ~410 TQ with required downpipe and healthy IS20 hardware. Results vary with dyno type, altitude, temperature, fuel quality, and vehicle condition.

ECU Tune Modification Requirements

Stage 2 hardware (quick view): A High flow exhaust is required. Intake and intercooler are strongly recommended for consistent power and heat control. A TCU/DSG tune is highly recommended where equipped.

Crackle Pops (Overrun)

Optional overrun/crackle in Dynamic/Sport mode. Subtle on stock exhaust; more pronounced with 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, sharper response, and smoother power through the entire band.

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.
