Ran across this product that for 100 bucks supposedly increased hp by 10-15. They have user testimonials on there as well. Just wondering if anyone on THIS site has actually used this or a similar product and got similar results. AND is the install really as simple as advertised for these things. Does installing one of these goon up your emissions/smog check as well (I'm in Cali)?!
Thanks in advance for the feedback!
