I just got my evo9 mr and have been reading alot about tuning and came to the conclusion I need a tactrix cable. If there is a better tuning solution someone let me know. I see on their website they have the 2.0 cable, but ive seen some threads say its not compatible with a evo 9 or its slower. Which cable should I buy? The older 1.3 or the 2.0? Thanks.
