E82 / E87 / E88 1 Series (2008 - 2013)
BMWs throw back to the iconic 2002, with a renewed form and function. The smallest car in BMW's line up but still packs a punch. Available in coupe or convertible, powered by a naturaly aspirated inline 6 in the 128 or the turbo twin power inline 6 rocket sled 135.

Dyno comparison to Jb4

I finally got to take my 08 135i over to a dynojet dyno to compare numbers. The car made a good bit more power on the dynojet than it did on the dyno dynamics. My car made 320whp on a dyno dynamics and 353whp on a dynojet.

I then compared it to the JB4 piggy back set up. Peak number very close, but look at the power past 5k especially. The true ecu tune is the blue line, Run 1.
