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
