Going from one big tuner to another won't make much difference, maybe a few HP in it
I heard that one of the Superchips mappers has recently gone to Revo - so you maybe paying the same again for the same map
R-Tech custom with tiv mapping will give you a set up tailored to your driving style, Free fault finding and a lifetime of aftercare. May only give a few bhp above bluefin but is cheaper and set up exactly to your mods. I'm yet to hear a bad word about them. . .
You pays ya money, you take your choice
