scotty

hi there I'm just wondering if anyone is using the coiltek 15" with the equinox 900 .I've been using it every now and then but I'm still not convinced with the coil .the main trouble is it can be a bit noisey even with the sensitivity turned down to 17 .i have tried some settings that ive found on line but always end up going back to my stock 11 " coil which is alot more settled .any advice guys .thanks .
