I have been doing a lot of testing on piggyback boxes for the 8AR-FTS motor and so far i've tested the RaceChip Ultimate, VRTuned, Burger Motorsports (not released yet) and Toms Racing from Japan. It came down to the Burger Motorsports (BMS) versus Toms Racing as the 2 top boxes on the market so i decided to get some official numbers on them.

Toms Racing Japan power box
TOM'S Racing Japan
+21.34 WHP
+29.68 WTQ
Burger Motorsports USA (BMS)
+22.81 WHP
+30.8 WTQ
