BR-Performance now offers two stages of tune for the BMW i8.
The Stage 1 tune, described as a "safe" tune, takes the BMW i8 to 400 HP combined, up from stock at 362 HP. Torque increases too from the stock rating of 420 pound-feet to 479 pound-feet.
The Stage 2 tune takes it even further, but BR-Performance notes that this tune isn't as "safe".
Stage 2 figures are 428 HP and 530 pound-feet of torque.
Pricing for Stage 1 is listed at 890 Euros. Pricing for the Stage 2 upgrade has yet to be announced yet.
