I saw this for sale and was wondering if anyone had any experience with these? Mainly will it cause any ill wanted damaging effects to my car? And are they worth the money? Thanks for any input on this!

 

dont waste your money on this, it is a total piece of ****. I had one on my accord. when I opened it up I found that venom filed off all the numbers on the chips so you couldnt duplicate it. The most expensive thing on the whole unit is the cord on it. I bet if you knew what chips it had in it, you could duplicate it for under $25. I didnt notice a difference with it. If you want the same effect, push the gas pedal further to the floor.

 

all I needed to know thanks mrnicolas!
