I’m having a good experience with my beta JB4...just installed a few days ago. I’m stacked Velos 2+ with JB4 on map1 and its a crazy rocket. I used to have to wait until around 3k rpm for the speed but now it flies starting at 1500 rpm. Way too easy to speed. I had trouble initially because I still had my P3 gauge hooked up and it interfered with the JB4 causing very odd engine behavior. Now I’m trying to trouble shoot a TMAP tap for boost only reading on it. I’m hoping to use the JB4 to run meth in the future also...and need to find a shop to upgrade the turbos
