i have a few questions about jwt ecu's... like i have stated in a couple other threads i am going with a fmax stage 2 type turbo kit... when looking at the kit it says requirs stand alone... does this mean it just needs jwt ecu? and basicle you send it in to him and he sends it back in 4 to 5 weeks... well i guess when i upgrade my cams or something i must send it in again, for more reprograming?? sorry guys i am not to knowledgable on how people do the jwt reprograming process, or afford it?
