All number uncorrected. Elevation of around 5200ft, temps in the low 70s in the building. Just installed NGK 5992s because I'd been getting some misses at high boost with the factory plugs even though they were only a few months old. Running 100% E85 and 16-17psi was too much for a 0.028" gap...had to gap down to 0.022" to make it go away. The standard correction factor for these conditions is about 20%, the shop normally uses 15% for turbo cars here.
