i got this wira 1.3 A/B yr 2000.....i think its a good car...enough for me for daily use....but there is only one problem, the pick up is not very good....usually when i want to go up hill eg, genting and also during overtaking....i need to use gear 1-2 to keep it moving.....is there any modification that can do to increase the pick up and also the engine response???

if possible...can u estimate the cost that will be need for the modification??
