I torque them to 18 ft-lbs. Below is my log. I'm running bm3 stage 2 93 octane OTS tune version 6.1. Loog looks super clean and timing is good. Timing advances to 10 degrees in the upper RPM range. I may get into the low teens with an E30 mix running the E30 map. I'll mix some E85 in the next fill up and see how that logs. Log below.

That's pretty cool. Thanks for posting. Curious to see your next log. Not surprising to hear that you started seeing some idle issues at 20k miles. That matches what I was told about the NGK's lifespan in a tuned car being about 15k-20k miles.
