Just picked up a JB4 piggyback tuner. Wanted to know if anyone else runs this? Maps1 and 2 adds about 3.5 psi boost.


Wanted to see if anyone else runs this. They work very well on other boosted platforms.

How has this been working for you and which harness do we order for our trucks?

I ran it on my 2019 F-150 2.7tt and it was great, wish I could plug it into my Tremor instead of buying another one.
 
I hooked it up to my Tremor a few days ago! I love it! Ran Map 2 for most of the time. But I put $100 of 93 and set to Map 3. Wow it’s got some major balls! I think going with an AM intercooler, air intake and maybe exhaust, I’ll run the higher Maps. I think the intercooler is the weakest link though. But with gas prices I’ll stick to 87 and Map 1-2 for now.
