Hi Experts, for the past one year i have been googling on Fiat linea 2012 and at last i will be getting one on 30th Jun 2012 from chennai. Also i have been listenin to various owners say very good things about the car and its built quality. After the reviews on the performance chips which will enormously change the way Indain linea works...! i would like to know few things before i purchase one from USA UK or Germany. 1. If i install the performance chip in the car - how much will it increase the mileage of the car? 2. I am not getting any thread on the emission level of the car after the mod??? anyone saw any difference? 3. By how much the life of the car/engine decrease (if at all)? my average use will be 1800km per month on highway ...! 4. Is it really advisable if i am planning to keep the car for LONG TERM -- lets say 10years? And last which permanence chip is the best (cost is secondary). Please advice as i am going to UK next months if above things are satisfied i will get one from there...! Regards, Senthilprakash.
