Now, see i disagree with ya there alltogether, i recently installed revo stage 1 to my GTI, and i had superchips bluefin stafe 1 onit before, and revo on mine is definetely alot faster, i'd say at low revs they're both the same but, after about 4-5k rpm the revo map i've got destroys the bluefin map, i felt like the bluefin died down at higher revs whereas revo's just wants keep on going. Does'ng stop pulling! So personally, i would highly recommend revo, especially atm as there's a 25% sale on! As i think revo and apr's power gains are nearly exactly the same so no point forking out the extra £££
