You seem shocked at 18 degrees but many are running locked distributors and int he 24 to 28 degree range from scanning all the turbo web sites. I have years of blown engine history and it would be common to run up to about 32 degrees with a fixed mag and no mechanical advance. I am learning boost is not just boost as the turbo are a different critter than my roots type blowers.
