Hey guys! Just wanted to update again. I am now at over 20k since I installed the JB4. Absolutely zero issues, very happy with this unit. I will install on the Raptor Bronco also, it’s worth it in my experience.

(10,000 miles UPDATE)
I have now put a tad bit over 10k miles on my 2.7 bronco with the JB4 unit installed. I am nothing but happy with my unit. Never have had any engine lights or issues to speak off. The power gains are not something I want to go without, I still have fun driving it. Might do WATER/METHANOL injection next for fun. I stand by my original review, and will update if I ever have an issue.

Hey guys, I wanted to go ahead and share my review/opinion of the JB4 tuner on the 2.7 Bronco. My Bronco is a 4 door Badlands w/Sasquatch, LUX, and is overall going to be a pretty extensive build. This Bronco is officially named the “Buck-Wild Bronco”, and will live up to the name. The engine will ultimately have a lot of performance mods done to it, but the engine was not the priority right now. This rig is ultimately a vehicle for vendors and my own accessories to be used and abused on. There will be many more posts about this Bronco but I wanted to start with a review of the JB4 install and real world experience.
DISCLAIMER: I reached out to Burger Tuning to see if they wanted to be part of this build. HOWEVER, my review is 100% honest and our agreement was that I could be 100% honest about the JB4. I contacted them because I believe in supporting USA made products and companies. I found them to be a company that I would be proud to support.
The TUNER: I want to start with the basics of what this tuner IS and is NOT. The JB4 works by tricking the computer into providing more power, it does this by piggybacking two sensors. This has both benefits and drawbacks. The biggest benefit is that you do not alter the OEM computer programming and essentially you are untraceable. You are also not VIN locked on this system and you could swap it to another vehicle if you trade in. The system also does not override the OEM safety programming, so you are not pushing the vehicle past the limits. Now the drawbacks of a piggyback tuner… It doesn’t control your transmission shifting, and it can’t override your OEM safety programming. But wait, didn’t I say that the fact it cannot override the safety limits was a good thing? Yes, it really is a good thing, unless you are planning to modify and improve the other weak areas of the drivetrain… You just need to know what your goal is.
The INSTALL: The JB4 came nicely packaged and the unit itself is very premium feeling. There are two sensor connections that you disconnect from the sensor, plug into the JB4 harness, and then plug the other JB4 wires into the OEM sensors. There is also an OBDII plug that must be run through the fire wall (see photos) but ford gave us a VERY easy access to run into the cab. I also opted for the bluetooth control, which plugs into the JB4 brain. I wanted the install the look factory, but I also did not want to place any screw holes in my Bronco. I HIGHLY suggest using double sided automotive 3m or gorilla tape, and grab a package of small black zip ties also. This makes the install a breeze, as in a 15min walk in the park. Please see attached photos for how / where I installed my unit. Overall I give this an A+ on ease of install.
The REVIEW: I think I should start by saying that I installed the unit, drove around, played with the different MAP’s and proceeded to grin as I was enjoying my bronco much more than before. I want to get something stated early on, the best gains are not felt from 0-15mph, this is because of the limitations of the JB4, remember it cannot overstep the factory safety net. Ford SEVERELY reduces the torque that can be applied to the wheels on a launch. This is because FORD doesn’t want to be paying for warranty claims when people fry their transmission from massive torque in a low gear. YES, I know we didn’t get the more robust 10r80 from the f150, I am still mad about that also… BACK to the review. Once you are driving around and using your vehicle like a normal person, the JB4 really shines. Passing, merging, and acceleration in general is greatly improved. It is a very noticeable improvement and I am still enjoying the bronco more because of this. My wife (not a car person) noticed immediately that the Bronco had increased power. She was missing the power and nimble feeling of the Taurus SHO that we recently sold, however she really enjoys the Bronco's "zippy" feeling now.
The VERDICT: Know what your goals are, if you want a solid improvement over stock, without hard flashing your factory computer, this is a fantastic improvement. If you want more extreme performance and are willing to risk powertrain damage (if you don’t upgrade the appropriate parts like a built transmission) than this isn’t for you. I can tell you with honestly that I am very content with this unit until my engine and transmission are built to appropriately handle the power I want. After having the JB4 installed, I really cannot go back to stock. I think that the JB4 is a great buy for 90% of people who want more power, without the costs of building a more robust powertrain. For those 90%, I give this unit an A+ and highly recommend.
PS: I didn’t do dyno runs, I highly suggest that you watch the LETHAL PERFORMANCE video that they posted about dyno results. Spoiler alert, it adds solid HP and torque. That Video is here!
