[QUOTE="Kyle_KleinSS, post: 14944239, member: 139281"] I just did 530/550 with a 2.8 upper 4# lower on e85. The lower is definitely worth it. The lower will give you the torque, not so much the hp. Yes in the upper rpms you will start to drop boost. That is because the 4v motors start to suck more air than the little eaton can move. Mine peaks at just under 18, and drops to about 13 after 5500 rpm. Hence why guys with lowers usually make the same hp as the upper only guys. However guys will a low make way more torque. Imo add the lower, you wont be dissapointed. [/QUOTE]
