BMW M235i

This beautiful little BMW came in already “tuned” with a piggyback JB4 box. The goal was simple: to have better torque/power than JB4 and still retain STOCK OEM reliablity.

Power (stock): 326 hp

Power (measured):stock, without cats 356 hp

Power (tuned): JB4 setting 2, no cats 382 hp

Power (tuned THP): 403 hp
