I have Bluefin Stage 2 and i wouldnt say its rubbish
I would choose Bluefin over Revo, purely because its maps are less agresive and higher torque which Revo's maps normally are excelerates wear n tear. So in my case wanting to keep my car long term, revo was ruled out for me.
The only issue ive had with Superchips is getting the correct map with transmission type.
I know my staqe 2 Ed30 is far from slow and with lower torque spike mid range allows me to put the power down with less wheel hop and traction on the front wheel issues.
But as your only keeping the car short term and planning on ragging its nutz whilst you own it, then go for anything you like
and let some other poor sod pick up the mainternance bill later
