still got ppl believe in those wat trd sprint booster thingy?....all aka snake oil...car's hp doesnt increase, just making ur right foot depress lighter but burning more fuel to feel car is more "responsive"
I used before and i like the responsive feel very much
Tested on my old car fiat grande punto before
In fact the fc improve after using it
People may say eat more petrol bla bla, snake oil bla bla
Its not a matter u believe or not
Its whether u like it or dun like it
Anyway im not buying a brand new one which cost 300+ la
Used one which cost less than 1/3 of the price still ok
