650 DP w/ milled and no other changes picked up .03-.04 consistently. W/ jet changes to match, picked up a total of .05-.06. That was in 1984 on my first car. Since then, I pretty much delete it right from the start. Anymore, I just buy a main body w/o it and go from there. Given that I "proved " the mod a long time ago, others may be getting different results today. I'm interested in seeing if others are going to back me up or tell me I'm full of it. Could be an interesting test on a modern engine. If an argument breaks out, I have the parts to swap around and test it. My car runs 12.30's at 110 at 5800' in elevation. The elevation itself is a factor that could change my results in comparison to a sea level motor, so maybe someone down low can also validate the results.
