hi Metro. I have a space grey e92.
I got m3 bumper and told myself to make it look good and leave the power mods.
I wanted a code reader and they were around $200 with full cable so I went for the JB4 for the extra value. I convinced myself on reliability mods, so I have DCI, ETS FMIC and my friend gave me his DP's. My next reliability mod will be ER competition duel Oil coolers : )
Get the JB4 .. it's a multi-tasking CODE reader : )
