| Stage 2 93 Octane + Downpipe | ~268 WHP | ~315 WTQ |
ECU Tune Modification Requirements
Stage 2 hardware (quick view): This calibration is built for a high-flow downpipe setup. Intake and intercooler are strongly recommended for heat control and consistency. Drivetrain inserts help tighten power transfer and reduce wheel hop.
| PART / UPGRADE | REQUIRED | RECOMMENDED / NOT REQUIRED |
|---|---|---|
| Air Intake | X | |
| Intercooler | HIGHLY RECOMMENDED | |
| High Flow Exhaust | X |
Crackle Pops (Overrun)
Optional overrun enabled. Subtle on stock exhaust; aggressive on freer-flowing setups. Tuned with RPM windows and exhaust temp safeties to keep it controlled and safe.
Boost Control & Drivability
From the factory, boost delivery can feel uneven on long pulls. BDT refines the curve for quicker spool, linear onset, and smooth repeatable power without surge.
Software Install Requirements
WINDOWS LAPTOP REQUIRED (NO APPLE)
| DEVICE | PORTS | OS | PROC. | POWER | RAM |

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.
