FBO 35i xDrive... Now what?
Hi there! I have a 2013 X1 35i full bolt on, with Jb4 G5 Iso and meth kit. Last time I dynoed it, 93 octane pump gas, the numbers where 338whp. I do know I can get a few more hp from the stock turbo (meth additive and fuel trims werent maxed out), but want to push to the whp to 400 barrier and i will need a turbo upgrade (Vargas, Pure, etc.). Terry @BMS told me I would need a back end flash (Cobb Accessport) but Cobb told me they dont support X1 35i. Any ideas how to work a turbo upgrade without Cobb's Accesoort?
