[stumpy]

I don't recall whether or not the 1050 comes with removable IAB's. If yours does, then try removing the middle IAB and see what that does. I had my 1050 Dom rebuilt by Nickerson Performance. It ran great on the track, but part throttle was very rough. At a dyno session the tuner wanted to make ridiculous main jet changes to clean up the low end AFR (it was pig rich). We call Nickerson and they suggested that I remove the intermediate IAB's (they make em all removable) and leave the mains alone. That one change made all the difference. It drives like a dream at part throttle and it improved my 60'. Before that I would not think of street driving it.
