If you go for bluefin, bear in mind it takes about 20mins to switch back to stock mode.
Bluefin drives more like the normal map, until about 4k revs then takes off. It is more fuel efficient than the revo, but not as quick. More people go for Revo on here, as it is more aggressve and feels quicker, and has more torque etc.
Revo can be switched back to stock in about 10 seconds.
Then again, I thought the PDtuning remap was better than the bluefin, but doesnt have the switchability of the other 2, but is cheaper.
I had an engine light come on with Revo stage 2+, swapped parts over, still there, so got a refund.
I'm currently in th progress of getting a shark performance remap, which also has the option of switching back to stock.
If you are wanting to know what a stage 1 remap is like. go to your revo dealer and get a 5hr free trial, after the 5hrs is up, the car goes back tostock power. But... if you decide to go to another tuner after the trial, you must go back to the revo dealer and get the ecu flashed back to stock, otherwise you could run into difficulties getting a remap from elsewhere, as there is a small amount of code stored in the ecu which wont let the likes of bluefin work afterwards.
