I have PBTE and TAB. Each unit is RM200. Buy both get slight discount, if you are friendly get more discount. hehe. Fits really well on persona and viva, i tested few members here using viva also cars became very responsive and rev became very light and car is so much fun to drive. Elegance persona will feels engine less vibration, gear change very smooth and acceleration is instant! Fuel saving is significant too for both car model. its best to fit PBTE and TAB to get maximum saving, of coz i have to do the proper tuning and installation for you.
