Most BMW owners want more power—but don’t know where to start.
At Tysautoworks Performance, we recently worked with a Connecticut BMW owner who wanted to take their daily-driven 340i/M340i from stock to something fast, aggressive, and reliable.
Here’s exactly how we did it.
🔍 The Starting Point
The car:
- BMW 340i/M340i (B58 platform)
- Completely stock
- Owner wanted: more power, better sound, and daily drivability
Like many drivers, they came in asking:
👉 “What’s the best way to make my BMW faster without blowing it up?”
🛠️ Step 1: Baseline Diagnostics
Before any upgrades, we performed a full diagnostic check to ensure the car was healthy.
✔ No boost leaks
✔ No engine faults
✔ All systems running properly
👉 This step is critical before any performance build.
💨 Step 2: Stage 2 Bolt-On Setup
We built a balanced performance package:
- Cold air intake
- High-flow downpipe
- Charge pipe upgrade
- ECU tune
💡 This is one of the most popular setups at Tysautoworks Performance.
📈 Step 3: Power Gains
After tuning and installation:
- Stock HP: ~320 HP
- Upgraded HP: ~500 HP
🔥 Gain: +170 horsepower
The difference was immediate:
- Faster acceleration
- Stronger turbo response
- More aggressive sound
🚀 Step 4: Driving Experience
The owner’s reaction after the build:
👉 “It feels like a completely different car.”
The BMW was now:
✔ Faster
✔ More responsive
✔ Still smooth enough for daily driving
⚠️ What Made This Build Reliable?
We didn’t just add power—we built it correctly:
✔ Proper tuning
✔ Supporting mods (charge pipe, airflow upgrades)
✔ Professional installation
👉 That’s the difference between a safe build and a risky one.
💸 Total Build Cost
Approximate range:
- $3,500 – $5,500
👉 One of the best horsepower-per-dollar setups available.
