where can i get it done in miami florida or if i have to ship it out where and what type of power gains do you get

 

Unfortunately us on the east coast arent having much luck having the high end techno jap doods being around to facilitate that for us. so tadashi in cali may be able to help you out. he reflashes the ecu and sends it back to you. hopefully he has tuned someone with the same mods as you so it will be beneficial, of course having a custom tune of your own is best but for now this will have to do.

Cobb is another company that is soon (i hope) to release a nice little gizmo that will let you easily plug it into your G and upload maps for different mods to your G, a custom tune map can be done with a big of datalogging and sending it to a CObb tuner to adjust your map via the logs and send you the new edited map.

you can read up on some tadashi info here. a member took his vehicle there and posted his experience with the entire procedure.

and here is some info on the cobb access port, all member discussions, but will get you familiar with the options we currently have soon to be available.
