e-rams suck, my friend got suckered at nopi and his car was pretty quick, when he put that piece of s**t e-ram on it lost power, they told him it would give him a 5 to 10 hp gain, he dynoed his car before and had 160 or 170 something and after it run a 155 hp, and they only give 1 psi, so dont get suckered like he did.
