Toyota Supra MK5 (A90 / A91) Tuning in Boca Raton, FL
GR Supra ECU & TCU Calibration Specialists – South Florida
The Toyota GR Supra (A90 / A91) is powered by BMW’s B58 turbocharged inline-6 — one of the most responsive modern turbo engines ever produced.
From factory:
- 335–382 HP (depending on model year)
- ZF8HP transmission
- Closed-deck B58 architecture
- Significant untapped calibration potential
At Egor’s Garage in Boca Raton, we specialize in precision ECU and TCU tuning for the MK5 Supra platform. Our focus is simple: safe, repeatable power gains with factory-level drivability. We proudly serve Boca Raton, Delray Beach, West Palm Beach, Fort Lauderdale, Miami, and all of South Florida.
Why the B58 Supra Responds So Well to Tuning
The B58 engine inside the MK5 Supra was engineered with significant headroom. Factory boost targets and torque limits leave substantial performance untapped. With proper calibration, the B58 delivers:
We routinely see:
- 430–500 WHP Stage 1
- 480–520 WHP Stage 2
- 600–700+ WHP with advanced fueling and turbo setups
Every result depends on fuel quality, hardware configuration, and calibration strategy.
B58 Supra ECU Tuning Options
Stage 1 is ideal for stock vehicles seeking immediate, reliable gains without hardware changes.
Typical Gains:
+70–100 WHP
+100+ WTQ
We refine: Boost control, Torque modeling, Ignition timing, Throttle sensitivity, Cold start behavior.
The result is a dramatically more responsive Supra without sacrificing daily drivability.
Stage 2 Tune (Downpipes Required)
For drivers seeking additional output, Stage 2 calibration optimizes airflow and turbo efficiency.
Expected gains increase significantly when paired with improved exhaust flow and intake efficiency.
Stage 2 vehicles often achieve 480–550 WHP depending on fuel type.
Flex Fuel & Ethanol Calibration
For serious enthusiasts, ethanol unlocks the S58’s full potential.
We offer:
- E30 custom maps
- E50 maps
- Full Flex Fuel integration
- HPFP upgrade integration
- Port injection tuning
Our ethanol setups are built around reliability — not just dyno numbers.
Toyota Supra MK5 TCU Tuning
The ZF8HP transmission is extremely capable, but factory torque limitations restrict full power potential.
Our TCU tuning includes:
- Increased torque limiters
- Faster shift speeds
- Improved launch behavior
- Optimized shift pressures
- Reduced gear hesitation
TCU tuning is strongly recommended for vehicles exceeding 500 WHP.
