well i have the one step colder ngk's (bkr7eix-11). im running boost spikes up to 11 (at highest) and then settles to 9-10 psi. keep in mind i have awr manuel moto mounts, find out why it matters after question. well my question is i seem to feel my car idling rougher. rougher then normal w/the mounts. could the colder plugs be dropping my idle, should i go with the normal range of 6? it idles around 650-700 rpm give or take (trying to remember). i'd greatly appricate if you guys (ladies included) could point me in the right direction. thanks for the time

take it easy

ya i have one step colder plugs, motor mounts and i have always had a rough idle. i guess i just got used to it. mine idle's around 650.
 
I had the similer problem when i first installed th BK's then i found out that the ZFR7F's are extended reach and Idle smoothed out some, yet they are still copper with short life spans
 
i have a bit of rough idle too. but i'm on stock plugs.... it's just the way this car is! you can try cleaning the EGR valve... or try using some SeaFoam like some people suggest.
 
(nana) (butthump) (naughty) (boobs2) chicks love feeling my sparco knob vibrate, gets em right in the mood. (colder plugs(v-groove or something) and solid mounts)
