should i go 1 step colder plug?
here's my setup for those that don't know me...10psi, d16y7, tdo4L, 450cc inj/afc hack, msd btm @ 1/3 degree per 1lb of boost. almost 9000 boosted miles on these plugs.
showing my ignorance just a little when it comes to plugs, but i checked them last week and they looked pretty good. they looked as though i had been running a little rich (which i had known since i was using a techedge at the beginning of august), but the strap was a little whiteish like there was some leanness. i haven't heard any detonation at all and there was nothing that shook out of the plugs. additionally the porcelin insulator and electrode looked new still. i didn't check them after a hard pull and shut down...just normal driving...boosting and then normal driving into my neighborhood and garage.
from what i can see it looks like i can keep using these, but i was looking to go to 1 step colder to be on the safe side. i'm using zfr5f-11 right now which is stock. i was thinking of going to zfr6f-11.
should i even bother doing this? i'm assuming my afr will still stay the same...it will only safeguard against detonation, right? i'm still using stock ingnition...i still should have enough spark, right? i don't seem to have any stuttering problems and it's very linear in it's power delivery and strong, but will it help anyway to shorten the gap from stock?

if I as you I would just shorten the gap a little if your plugs look ok as they are. How long have you been turbo? Check them in a couple of weeks and see how they look then. If they look bad go 1 step colder. Either way 1 step colder wouldnt hurt any.
