I bought the JB4 back in October right after I bought my 2021 Accord 2.0T Touring. Being my first new car ever, (wifey gets the new ones) I kind of wanted to keep the warranty somewhat intact. The JB4+ wifi was an easy install and the power increase was evident. Map 5 E30 is the real deal. Then temptation set in and I bought a KTuner used for $350. Getting rid of 126 mph governor was awesome! Then Dan Villa (YouTube) who turned me on to JB4 started showing KTuner Stage 2 and then Stage 3 videos. I HATE YOU DAN VILLA! Not really! Got love for ya brother! I got a great deal on a PRL HVI and the insanity starts. UPS is delivering Upper/lower mounts and the performance addiction rears its beautiful head! This is my daily driver that I will put 25-30k on per year. I have a 1987 Buick Grand National (3.8 Turbo) 470rwhp/540rwtq (11.18 @122) and a 1980 Z28 420rwhp/ 410rwtq in my garage! I'm semi old school, but needed milage since I drive 133 miles on way to work, twice/ week. The Accord fit the bill perfectly! I contacted Terry Burger @ BMS about stacking the JB4 on top of the Phearable Stage 3. I sent him logs of the Stage 3 and he looked at the logs and we started playing! We moved to Map 1 with E30 and the logs looked great! I run 11 gallons 93 & 4 gallons of E85 for a E30 mix. Car is .33 seconds quicker from 60-100 mph! Probably 20 hp more. I have no traction below 35 mph! Car pulls hard! That's 3 cars in quarter mile! JB4 is the real deal in performance. Check out Five Star Tuning on new Ford Bronco. JB4 maps added lots of power/torque! Terry @Burger Performance is awesome and responds quickly!
