Anyone uses this broquet before?
Heard that this actually save fuel & increase the horsepower of the car?
Anyone got better recommendation to increase the horsepower?
THe results is not really very obvious..... depending on how much HP you will like to have...... and of course how much cash in hand..... basically even if you spend $800 on the toal package as advertised by MCwell..... it will not improve by much.... 5 HP maybe.....
