Vios tuning at Rs Dynotune

Robyn from RS Dynotune has a new product called EFR. Theres stage 1 & stage 2. According to him it can do fuel and ignition tuning. For more info on the product please contact him. I sent my wife vios to install the EFR Stage 2 and quite happy with the results. For those not familiar with dyno tuning can see the pictures and videos below.
