Ah, OK, might have helped if I actually read "Battleground" in your first post, lol... But let me ask you this: Had you heard that out 92 octane is actually very good and 93 tunes run well with no problems? I had asked early on and got some good feedback from others in our area that tuners who had worked with previous NW customers that we indeed have good quality gas, more like 93... so I've been running the Cobb 93 tune, which is pretty aggressive and have had zero issues, my OAR stays at -1.0 (the best) almost ALL the time, very occasionally will hit -0.99 but it's been a long time concern for me now resolved: We simply pretty much have 93 here!
