Since I'm at a higher altitude, I got the stock heat range. Stilov played with colder plugs, and found the stock heat range to be better for as high as we are in Salt Lake City, Utah.
He was running less boost with his old setup, but had a higher CR and a "decent" air to air top mount IC. I have about 9.5-9.75:1 and will be running a bit more boost.... but with what should be a really efficiant water to air IC.
What are some thoughts about this?
