Hi,
I was looking over for some accesories for the RSX on Ebay. And i noticed many performance chip for the rsx. They say it could gain up to 20hp.
For example I saw. "INTAKE SENSOR CHIP FOR ALL ACURA RSX (20 hp gain)" for about 5$ +shipping. or "02-05 Acura RSX Performance Chip/Module+25HP" for 25$ + shipping.
they says it doesn't damage the car....
it this actually worthed? does it work. i guess the numbers are not true but does it give a little boost?
is there a catch to it?
