640i and JB4
Anyone running a JB4 on a 640i?
I am looking at adding one (new version with OBDII connector) on my PWG N55. I am a little wary because it seems that the F1x platform doesn't get the same gains as the F3x, and has more problems as well (continuously running wtaerpump etc). Any first hand experiences? What kind of gains did you guys get? Is it a worthy mod or not? |
