Juice box/ JB removed from BMW 335i

JB3/Juice Box piggy back system being removed from a BMW 335i, car had lumpy power and also engine lights. All back to standard, now for a proper remap! ECU fault coded where being hidden from scan tools. Once it was removed we where able to clear 15+ fault codes!
