Bronco Raptor Gets TUNED! - JB4 from Burger Motorsports



Let's be honest... You had to know we weren't keeping this thing stock, right? 


Especially with the capability these motors have shown in their original platform, the Explorer ST, we had to start the journey for more power. Luckily, Burger Motorsports has made it easy with their JB4 Tuning Device. 


Just like our testing on a First Edition, 2.7L Sasquatch Bronco, we ran the Raptor through testing, from 0-60's to getting real number gains from the dyno.  Once again, we're thrilled with the result and the HUGE gains this device is capable of.

Installation Checklist 

- The JB4 (and any accessories optioned for)

- Zip ties

- A sharp knife

- Heavy Duty, Double-Sided Adhesive Tape. 

- 2.5MM Allen Key (for Wireless Connection Kit) 

- Small Phillipshead Screwdriver

- 10MM Socket or Wrench

- 7MM Socket

-  8MM Socket 


1. To start, of course disconnect the negative battery terminal using a 10MM socket or wrench. 

2. If you have the Wireless Connection Kit, take a 2.5MM Allen Key to remove the cover from the JB4 so you can access the plug for the Bluetooth Adapter. 

3. Plug in the connector in and install with the supplied Phillips head screws. Place the cover back down with the allen head bolts and evenly tighten to ensure a good seal. 

4. Figure out how you would like to run the OBD2 Data wire from the interior to exterior. (As seen in the video, there is a grommet we simple sliced a small slot in so we could just barely get the plug through and have it seal back up.) Then run the wire through and make sure there is plenty of slack to ensure you have enough wire to mount the JB4 where you would like to. 


Next, it's time to start plugging the JB4 harness into the OE Harness and Sensors. 

5.  Using a 7mm and 8mm socket, loosen the clamp and bracket holding the intake tube to the top of the motor.


6.  Using a 10mm socket, loosen the bracket covering the MAP sensor and carefully pull it away from the sensor. This should allow for suffice room to access the MAP sensor. 


7. Unplug the MAP sensor harness and replace with the JB4 harness. Then plug in the corresponding side of the JB4 harness into to the vehicles harness.


8. Re-Install the Intake Tube and Bracket. 

9. Now, find your TMAP Sensor (inline sensor just before the throttle body) and do the same as previously done on the MAP sensor. 

10. Find a safe routing for the wiring. (See video for how we routed, but overall, there's a few different options depending on where you want to mount the JB4 Device.) 

11. Once you've decided where you would like to mount the JB4, take some weather resistant double-sided tape and stick it to the surface. (We personally attached it to the fuse box but the choice is yours) 

12. Mount the Bluetooth Adapter using the same tape. (Burger Motorsport recommends not mounting this adapter on metal) 

13. Plug the OBD2 Harness into the coordinating harness on the JB4. 

14. Install the negative harness back onto the battery terminal. 

15. Go for a rip! (Download the JB4 App and run through the dialogs in the app if you have the Wireless Connection Kit) .



Next day after install, we hit the dyno! 





Check out the Dyno Testing video here! 

Drivetrain losses were fairly significant, although with a wider and heavier wheel and tire combo, it's wasn't unexpected by any means. Although, at just about 100HP and 80TQ lost in the drivetrain from the Ford OE Rating, it justifies the JB4's purpose. We tested every MAP the JB4 has to offer, starting with Map 0, which disables the JB4, essentially turning the truck back to stock.



Stock, the Raptor made 317 RWHP and 358RWTQ. Not impressive by any means but certainly a solid jump from the 2.3L and 2.7L Bronco's. 


Map 1, as the device comes preloaded on, provided an instant 15 RHWP and almost 50 RWTQ gain, starting off with an aggressive jump in power! 


Map 2 gained us roughly another 7 RWHP and 1 RWTQ. Nothing too impressive, but with rapidly rising IAT temps after Map 1's runs, we weren't surprised. 


Map 3 gained us another 8 RWHP and 4 RWTQ. While we did let the Raptor cool a bit before running this Map, it did not provide a significant change, but still a gain. 


Map 4 gained us 16 RWHP and 15 RWTQ. Of course, this was after adding some octane booster in order to meet Burger's recommendation of either E30+ or Race Fuel to avoid knock. 


Map 5 gained us another 16 RWHP and 5 RWTQ. Another solid jump in power with just the push of a button! Although, during the run of Map 5, you can see a dip in the graph where we believe either knock occured OR the Raptor's PCM detected a torque value exceeding the factory set limit, and therefore attempted to limit torque. This would make sense, as it showed this dip in power near the peak torque RPM. 



Overall, you're looking at a solid gain of 62 RWHP and 74 RWTQ!

All of which took less than 20 minutes to install, can be controlled and monitored through your smartphone, and is totally untracable. 


Notes for Testing : This testing was conducted in the closest ratio possible to 1:1, 6th gear. While 7th gear is actually a 1:1 ratio, the vehicle's speed limiter would not let us make a full pull, even with the "Dyno Plug" unplugged. 





After the Dyno, we finally hit the (CLOSED COURSE) streets to get some real world results with the JB4. 


Check out the full video of our 0-60 Runs here! 


Stock, the best time we could produce out of the Bronco Raptor was 6.25 seconds. Overall, expected and not bad, considering the truck's almost 6,000 LB weight along with the larger wheels and tires, but we knew it could do better. It just needed a little... positive influence! 

Enter the JB4!

We started with Map 5, as we wanted to try for the best time before the truck started to suffer from heat soak. While we achieved 3 Consistent 5.80's and a couple 5.85 - 5.88's, we felt the truck had more to offer, which, (spoiler alert) it did! 
On Map 1, we gained roughly a tenth of a second in the 0-60 over stock, achieving 6.17 seconds
On Map 2, we achieved 6.10 seconds
On Map 3, we made a slight increase to 6.09 seconds.
On Map 4, we jumped to 5.72 seconds and confirmed it with the next run, clocking 5.78 seconds
Perfectly in corelation to the dyno sheet, Map 4 was overall a better performer than Map 5, due to what we believe the OE computer cutting time ans limiting torque 

Overall, we were able to drop over half a second, simply by installing the JB4!

0-60 Testing Notes
- For the stock runs, we tried various drive modes, but found Sport with T/C Off to produce the best results.
- On the JB4 Runs, an octane booster was added to the fuel to ensure a high enough fuel quality for Maps 4 & 5, since Burger Motorsports recommends either race gas or an E30+ blend. 
 - Each 0-60 was essentially back to back without a cool-down in order to record the most accurate, real world results.
