The company’s specialist have optimized the turbocharged 3.0 liter straight six engine’s ignition, fueling and turbo boost settings, using both chassis dyno and road testing.
Superchips has upgraded the 135i’s power from a measured standard output of 315 hp to 360 hp, with a maximum power gain of 49 hp at 5,989 rpm. At the same time, the ECU remap brings the BMW’s torque up from a tested 394 Nm to 456 Nm a 3,359 rpm.
“Compared to the standard BMW 135i, the Superchips upgraded car produces peak torque over 1000 rpm lower down in the rev range, making it not only ultimately faster, but also significantly easier to drive. Although not yet tested against the clock, the Superchips remapped BMW 135i is expected to better the standard car’s 5.3 second 0-60 mph sprint time, although for safety reasons the 155 mph speed limiter is left untouched,” stated the press release.
However, the extra-juice doesn't come with an extra-sip, as the Superchips ECU remap does not make the straight six thirstier.
“The Superchips BMW 135i ECU remap also scores at the pumps – when driven on a like for like basis with the standard car owners will experience no fuel consumption penalty, despite the extra performance,” stated the press release.
The modification is available for both manual and automatic transmission version of the BMW 135i produced from 2007 onwards and has a price of 445 pounds.
