Somebody Explain BLM's to me?
i know very vague stuff on it. After my heads and cam swap with stock ship i'm getting about 125-129 at idle 128-128 at 1000 rpm and about 119-134 when i give it gas. Is under 128 adding fuel and over 128 leaning it out. what do my figues mean? I'm clueless. I thougth they would have used just one number. how can it be lean and rich at the same time? Thanks
