Terry jumped on my issue right after he returned to work. Anyone have a similar experience? Have not reached out to BMS customer service yet, but hoping for some possible experience related advice from here. Unfortunately, even though my car feels like it downshifts smoother, my 'butt dyno' is feeling a significant loss in power, significant to the point that my car feels like its constantly in A mode when I ONLY drive in D. Started in Map 1 and switched to Map 2 for the little jump in boost, and off on a test drive I went! Downloaded the JB4 drivers and program to my laptop (Windows) followed directions, and successfully connected. Connected each of the proper plugs and hooked the unit up in the typical intake spot thats listed in the install guide. Received it earlier today, found an easy push out rubber grommet to run the OBD II line through (not sure why its not mentioned on here, seemed like the obvious choice, directly above the wiring harness is a thumb sized grommet you just push out). Dealing with some issues with my JB4 as well.
