COBB Tuning AccessPORT Stage 1 335xi vs. 335i JB3 roll on race videoHere we have a direct comparison between a 335 with the Cobb Tuning Accessport Stage 1 vs. a 335 with a JB3 2.0, Stett CAI, and Stett charge pipe. The JB3 car pulls but it is important to note it is RWD vs. an AWD car so not exactly apples to apples. Also, we assume this was pump fuel. Still, great to see a comparison like this.
