iv never had jabba, but iv had revo wich give you a suden power spike then fades off and now iv got a custom code wich is a softer spike but holds longer this is my view and both can be changed with exstas,
both would be around the same as a remap would put you up around 200 bhp but the clio is lighter.
 
depends on the driver, conditions, and many other variables, but i would guess a mapped cupra should really "sort" a clio 182 out off the lights, the strong point for the cupra (esp. in remapped form) is the torque, in reality top speeds and 0-60's don't mean a huge amount, its more about 3rd gear roll-on (30-70mph sort of thing) and my money would def. be on the cupra for that...
 
depends on who maps the car. it should be the Cupra cos the Cupra is Turbocharged which will enable it to make more torque. i intended to get a jabba re-map but then i was recomended to try somone else... which i did and im very happy. I went for a custom remap while driving the car. My results are down there. :D
