had revo on a K03, it dies terribly at about 4500rpm, and drives more similar to a diesel, massive amount of torque low down
unfortunately i can't find my graph from a RR with revo on (although of course different to the APR chip, but still there will be similarities because of the K03 turbo)
massive heat soak, unless you have an uprated FMIC, but still if you want true power and a cheapish upgrade then stick a K03S on and it can be mapped to about 245bhp, with a few other toys of course...
