[QUOTE=G2020VISION;25831996]Just ordered jb plus for my g20 m340. I don't have the time or the involvement as i used to have when I was younger tuning cars. I know you can up the boost max an additional 4.5psi. I purchased the jb4 and returned it with everything needed cause I don't want to go crazy on the car mapping and busting through the firewall. Really Waiting for Dinan to drop some decent mods so I am in warranty world lol. [/QUOTE
BIG FYI BMW warranty does not support or cover any mods including DINAN... except if its a BMW direct power kit
