We use E85 or Meth on this side of town; havent seen an N55 need a walnut blast (n54 days).
I'll inspect plugs and make sure they look healthy and are properly gapped so far 8k miles on Flash, had jb4 for 6 months.

I think when you're tuned just plan on replacing the plugs more frequently. Just kinda comes with the territory.
BTW how's your BM3 tune holding up compared to previous configurations you've had? |
It's amazing, the support, smooth power, doesn't fall on its face after 5500rpm, beating jb4/active8 lighter cars from 30-110mph until their weight advantage and aerodynamics come into their favor lol. Ran a few m235/335 flash tuned as well (I like to test my tweaks against friends).
Bootmod3 on 93 making better powerband than when I had jb4 with e30 mix

Plugs on tuned cars should be replaced every 8-15k miles depending on how much you drive, how hard you drive, how aggressive is your tune, what fuel you use, mods and how your car feels.
