Unlock your BMW's true potential with Bootmod3, MHD, and custom ECU maps. Stage 1, Stage 2, and custom dyno-tuned performance for F-Series and G-Series.
From mild to wild — we have a map for every driver.
Optimized for stock vehicles. Gain 50-80 HP and 80-100 lb-ft torque without any hardware changes. Safe, reliable, and fully reversible.
Requires upgraded intake, intercooler, and downpipe. Gain 100-150 HP with aggressive mapping. Track-tested and dyno-verified.
One-on-one dyno session with a professional tuner. Custom maps tailored to your specific vehicle, fuel, and driving style.
Optimize shift points, torque converter lockup, and paddle response for ZF 8-speed and DCT transmissions.
Aggressive overrun maps with loud exhaust pops and burbles. Adjustable intensity and timing.
E85 flex fuel support with automatic ethanol content detection and optimized timing/fueling maps.
Choose the right performance package for your BMW.
We tune all major BMW powerplants.
2.0L turbo 4-cylinder. Stage 1: 270 HP, Stage 2: 310 HP. Great entry-level tuning platform.
3.0L inline-6 turbo. Stage 1: 420 HP, Stage 2: 480 HP. M2/M3/M4 power levels.
3.0L inline-6 turbo (modular). Stage 1: 450 HP, Stage 2: 550 HP. Massive potential.
4.4L V8 twin-turbo. Stage 1: 650 HP, Stage 2: 750 HP. M5/M8 territory.
From purchase to performance.
Buy your map and download the flash file to your Bootmod3 or MHD app.
Connect your ENET adapter and flash the map directly to the ECU. Takes 10-15 minutes.
Start the engine and feel the difference. Monitor performance via the app dashboard.

Figures are approximate and depend on fuel quality, ambient conditions, and vehicle condition. Custom dyno tuning may yield different results.
Every map is tested on the dyno before release.
Tested on a 2021 G20 M340i with 93 octane. Stock: 368 whp / 390 wtq. Stage 1: 455 whp / 480 wtq. Air-fuel ratios remained conservative at 11.8:1. Knock sensor activity minimal. Safe for daily driving.
Tested on a 2016 F32 435i with full bolt-ons. Stock: 305 whp. Stage 2: 420 whp / 460 wtq. Performed 20 consecutive dyno pulls with consistent power delivery. Oil temperatures stable with upgraded cooling.
Tested on a 2023 G80 M3 Competition. Custom E50 blend map produced 620 whp with methanol injection. Ignition timing optimized for 26 degrees peak. Custom overrun map with adjustable pops.
All production maps include 15-20% safety margins on knock sensitivity, EGT limits, and fuel trims. We monitor 50+ parameters during validation including lambda, IAT, oil temp, and timing correction.

Stage 1 maps are calibrated for 91-93 octane (US) / 95-98 RON (EU). Stage 2 typically requires 93+ octane or 100 RON. E85 flex fuel maps support blends from E30 to E85 with automatic ethanol content detection via flex fuel sensor.
Most Stage 1 maps require no hardware changes. However, an upgraded panel filter and high-flow downpipe can improve spool and reduce backpressure. Recommended for all turbocharged BMWs.
Full bolt-ons required: cold air intake, front-mount intercooler (FMIC), catless or high-flow catted downpipe, and upgraded fueling (LPFP for N55, HPFP for B58). Cooling upgrades recommended for track use.
For sustained track use, upgrade your oil cooler, add a transmission cooler (ZF8), and consider upgraded brake pads and fluid. Stage 2+ maps should not be used for more than 3-4 hot laps without cooling periods.
