Little unfair to call superchips "cheap" they provide maps for plenty of cars and have a fair reputation.
I have the bluefin on my fr and it does what I need. Not saying it is better than any other. From what I understand Apr/revo would achieve better results but I wanted a product that can be completely removed as opposed to something that can be switched. Bluefin provides a nice amount of extra torque and bhp that you can feel. Haven't had mine on a RR since I have had bluefin, not sure I am that bothered. Had the map around 6 months now with no complaints.
Edit: forgot to add that it is dead easy to install. Took about 20 mins once they sent me the map. But the instructions are clear and simple.
