Yeah i got my 1.2TCE Clio mapped at Ktec, it was the first TCE clio they had done and went from 112bhp (standard) to 129bhp on the rolling roll.. The torque gain was incredible tho, the guy at ktec told me it was making similar torque to a 197
Felt very responsive but i eventually got rid and bought a 182 instead
Only issues i had with it were, occasionally when changing gear quickly from the max 6,800rpm the car would start to pulse the power on and off until you took your foot off the accelerator and re applied it. This only happened once or twice a week and only when the car was driven hard for while.. I think it could have either been injectors at max capacity or the fuel pump not having a high enough flow. Either way ill never know now as its gone to a new home
