I really like my SV1. idles good and worked great only time at the track! never messed with it at the track at all (3300DA) did some wideband street tuning but I need to get back out! sorry didnt compare it to anything but it worked good first shot down the 1320! mine is over 1200cfm!

just wanted to see how low I could get it to idle here.
