If I were to run an open loop tune, then it would be 100% gone but I elect to not run an open loop tune for the increased MPGs and overall reliability. The motor just wants a bit more gas than the PCM will allow at the affected conditions. Again not a real big deal.
I am going to replace the cam due to the pump drive gear issue and am going to give a 110 LSA a shot to see if helps to reduce it further.
The MWC and 4.11s are great but I am considering on going back to 3.90s which IMO are better for a street hot rod. The 4.11s are better for the strip. With the 4.11, my 1st gear is almost useless on street tires, just lights them up every time even when easing it out.

What I feel is at low load, low RPM and when simply cruising under low load. It is not severe at all, just a little annoying. Anyone else may not even ever notice it. My tuner went to great lengths to get it where it is and its not worth spending lots of money to further eliminate.

Looking forward to seeing your dyno #'s as well with those 21* heads! I almost regret not putting a more aggressive cam like your guys cam. I might have gotten more power out of my heads especially after the extra work Jason Short and his boss said they put into these LE2 heads.
