Long time lurker here but, I have some advice that might help. I spent many hours tuning a single and dual blow through setup for two different sandrails. I still run the dual blow throughs idf's on mine. (both with turbo)
Have you tried going down on the Main and Down on the air correction? - make sure you do both at the same time if you ahven't yet - I can't give exact 1:1 changes but I would probably try a 140 main, 160 air correction first. but, since you have the wideband, this would be my recommendation - This type of changes has helped me adjust that cruise a/f without sacrificing my on boost a/f.

Re: Supercharged Idf rich at cruising speed
Yes, I been down to 125 main and 160 AC. That's the point where it gets lean at higher RPMs and under boost but still rich at cruising. Im about to adjust the float again, that seemed the work with the bigger venturi. Thank you
