Car stock made less than impressive numbers, I was wondering why that could be - figured, do upgrades and see if they're made up for. Low and behold, they weren't.
Stock baseline 360/365 horsepower, post JB4+downpipe/exhaust, only made 390's whereas I've seen other (Z4 M40i btw) make 380s-390s stock, and more like 430's DP/JB4. In fact, per the JB4 forum one of the guys there made 433 on map2 with 91 octane, I'm not even breaking 400 with 93 octane and EWG installed. Made 30 horsepower/70 torque, but the horsepower numbers are very low. All things considered, what are the biggest contributing factors out there to look for in figuring out what is causing those drops?
