Also, I did get in contact with BMS reps via email and both of the person i talked to said that when using their JB stage 1 for N20 engines - it will be invisible / no CEL or code - basically its safe without the need to delete these codes when going in for service. I wonder if this true. (Ofc to detach all tunes bfr going in to dealer).

I need real tuner whom have used JB1 and serviced their car under warranty with no problem. Anyone?

Replies much appreciated.
