FREQUENTLY ASKED QUESTIONS
01
How does my tune get into my car?
Flash It Yourself (BDT Flasher) — Most of our 2015-and-newer cars (see the full list on the BDT Flasher page). Pick your BDT tuning cable at checkout (OBD2 to USB, OBD2 to Type C, or the Mobile Phone Flasher). Download the free BDT Flasher for Windows or Mac, sign in, and your tune is already on your account. Plug in, hit Flash, done in about 15–20 minutes. No appointment.
Remote Flash (we do it) — Older cars the app can't flash yet, like the MK6 GTI / Jetta / GLI, the B8 / B8.5 A4 / A5 / Q5, the B6 A4 and the supercharged 3.0T Q7. After you order, we book a remote session, log into your Windows laptop over screen-share and flash your car while you watch. Each listing tells you which way your car is flashed.
Plug & Play ECU — We ship you a pre-tuned ECU (the vehicle's computer). You remove your stock ECU, plug in the tuned one, and drive. No laptop needed. This is how our B7 A4 2.0T tunes are delivered.

02
What stage tune should I get?
Stage 1 — Stock hardware, big gains. No modifications required. Best starting point for most customers. Runs on 91 or 93 octane.
Stage 2 — Requires a high-flow exhaust. More power, more torque, more aggressive calibration. E85 flex fuel available on supported platforms.
Stage 3 — Hybrid or upgraded turbo. Maximum power. Requires supporting hardware (intake, intercooler, high-flow exhaust, fuel system). Built for serious builds.
Not sure? Text or call us at (843) 891-6687 with your mod list and we'll recommend the right stage.
03
What do I need to flash my car?
Flashing it yourself: a Windows or Mac laptop with the free BDT Flasher app and the BDT tuning cable you pick at checkout (OBD2 to USB or OBD2 to Type C) — or the Mobile Phone Flasher and your phone. Add a stable internet connection and a healthy battery or a battery maintainer (the flasher doesn't monitor battery voltage). No appointment needed.
Remote flash (older cars): a Windows laptop with internet and screen-share software, our OBDII cable in the port and a battery maintainer on the car — we do the rest.
Either way it takes about 15–20 minutes and is done from your driveway. No dealer visit. Full step-by-step support via text, call, or email throughout the entire process.
04
How long does it take to receive my tune?
BDT Flasher cars: your tune is added to your BDT account when you order — sign in to the app and it's there. Your tuning cable ships to you, with tracking by email. Don't see your tune? Text us and we'll set it up.
Remote flash cars: we reach out within hours of your purchase to book your session. Your custom calibration is typically built within 24 hours of reading your stock file.
Plug & Play ECUs: These ship via USPS. Please allow standard shipping time. Tracking is provided via email once shipped.
05
How can I track my order?
Once your order ships, you'll receive an email with tracking information. If you haven't received tracking yet, your order hasn't shipped — please be patient. Note that USPS tracking can sometimes be delayed and may not show movement until the day of delivery. If you have concerns, reach out to us directly at (843) 891-6687.
06
Can I go back to stock?
Yes. The BDT Flasher keeps the stock file for your car, so you can flash back to stock any time from the app and re-flash your tune later. On remote-flash cars your stock file is saved during the first read; book a flash back to stock session and we flash you back. For Plug & Play ECU customers, simply reinstall your original ECU.
07
What about warranty?
Aftermarket ECU tuning may affect your factory warranty. However, under the Magnuson-Moss Warranty Act, a dealer must prove that the modification directly caused the failure in order to deny a warranty claim. Many BDT customers daily drive their tuned vehicles for years without issue. We always recommend doing your own research and making an informed decision.
08
Do I get free updates if I upgrade my hardware?
Yes — lifetime calibration updates. Switch to E85, add a bigger turbo, upgrade your intercooler — send us your updated mod list and we'll revise your tune at no extra cost. Your calibration grows with your build.
09
What fuel should I run?
Most customers run 91 or 93 octane — most listings ask your octane when you order. On our MMS cars, multi-map switching lets you change maps on the fly, and you'll always have a valet/stock mode map as well. E85 and true flex fuel tunes are available on supported platforms with an ethanol content sensor installed (the sensor is sold separately).
10
Do you offer technical support after purchase?
Yes — full support from start to finish. We walk you through the entire flash process via text, call, or email. If you ever have issues, questions, or want to adjust your tune, we're here. Contact us at (843) 891-6687 or Boostdynamictuning@gmail.com.
