I recently tuned my 96 850 Turbo, now it starts to lope when I put it in gear

What is your question?

It runs great out on the road, and it idles good too, but when I put it in gear or turn the AC on it starts to lope like it has a racing cam in it..it has a recent full tune up.. I can unplug the idle control sensor and it kills the engine, same with the mass air flow sensor..any clues?
