You would need to get that dell up a bit assuming you are running V3/4 coils. Try 3.5 to 4ms

Check that the MAP sensor is reading correct and hooked up.

It should read 100ish KPa at key on and then much lower  when engine idling.

Is it rich right through? or is it rich at the bottom end and leaning out up top?

The base map is only a starting point, a full tune must be done.
