How Far
Do You Go?
Stage 1
ECU Remap Only
Pure software. OBD flash in 2 hours. The M177 leaves 100+ horsepower on the table from the factory — we take it back. Boost pressure, ignition timing, fuel maps, throttle response. All parameters stay within hardware safety margins.
- ECU remap via OBD
- Boost optimization
- Ignition advance
- Throttle calibration
WHP GAIN
+80–120 WHP
TORQUE
+100–140 LB-FT
STARTING AT
$800–$1,400
Stage 2
ECU + Hardware
The exhaust note changes. Downpipes open the turbos up, the intake pulls colder air, and the remap exploits both. This is where the car starts sounding like the brochure photos looked.
- Stage 1 remap
- Catless downpipes
- Cold air intake
- Charge pipe upgrade
WHP GAIN
+140–200 WHP
TORQUE
+160–240 LB-FT
STARTING AT
$4,400–$5,600
Stage 3
Full Development
Billet turbo wheels, port injection, E85 capable. The factory engineers would void the warranty on sight. Quarter-mile times that require a helmet at some tracks. Not for the faint-hearted.
- Stage 2 package
- Upgraded turbos
- Port injection
- Full ECU development
WHP GAIN
+200–300+ WHP
TORQUE
+240–380 LB-FT
STARTING AT
$9,800–$15,000
