What Idle MAP pressure w/ H/C/I swaps do you generally see? With a 216/220, .556/.564, 114 LSA, -10 overlap, ported LS6 intake, & AFR heads, the MAP was 42-46 kPa. With a 224/224, .596/.596, 114 LSA, -2 overlap, I'm seeing 54-58 kPa. Does the new idle MAP pressure look about right to you guys? Seems OK, just wanted compare what has been seen. Thanks

I'm seeing about 51kPa from a 224/224 on 116 and a
700RPM idle. Probably would go down if I bumped the
RPM up. Idle mixture and spark have a lot of effect
on MAP and you can use MAP movement to tell what
it "likes" as you change them.
