Ross/Paul, did GM change the MAF table for the 04/05 LLY's to increase the MAF's scale above 500G/s (The LBZ goes up to 583G/s, but the scale goes up to 800G/s)? I seem to recall at some point the last few entries in the MAF flow rate table having the blue border indicating it had been changed when it hadn't been changed since it was opened.
