I'm looking to tune my 2007 e92 335i this weekend. Going to order the JB4 + BMS DCI online and probably get a trunk meth kit sometime after. Anyone recommend a tuning shop in GVA to help me with this? Gonna need a mechanic patient enough to run me through how the maps work and if I get the BMS Trunk Meth Kit, do I need to buy a meth elbow/bung?
If there are any private mechanics out there who are willing to offer their services to tune my car please PM me.
I know CG Motorsports in Richmond offer tuning services, but I'm not sure if they're experienced with the JB4 / other BMS products.
