Soon after I got my 1998 916 it was Dyno'd and found to be running so rich the mechanic speculated the fuel was washing the barrels dry, topping up the oil, acting as an expensive coolant, etc. I was getting only about 80 miles to a tankful, and it never ran above 140 degrees.
He halved the problem there and then whilst rigged up to the dyno by backing off the potentiometers and properly setting up the air mixture screw, but the complete fix was to get a FIM chip put in, as the one that came with the cans (Arrows) was just crap and went straight in the bin. So you need to get it set up on a dyno, with a programmeable chip in my limited experience.
