hi guys dont know if any of use can help i have a 1.2 clio campus sport 56plate it has a full de-cat and a shitty cheap cherry bomb back box exhaust ive had a few pops and bangs when i change 1st-2nd a few times but im looking to get it to sit and spit pop and bang when stationary , ive had a flame spit once f**k knows how that happened ... theres a few clios round near me mainly the 172 and 182 and they seem to pop and bang all the time. ive been told to get it mapped but on a 1.2 its pretty pointless as there wont be much gain. any help ?
