You retarded the injection timing from where you were used to having it, and you're not too happy with the results? How about doing what an old Saab mechanic I knew insisted on doing with ignition timing and set it where it runs best? (which is often a bit more advanced than factory, on a 30 year old car it shouldn't matter much to trade a little cylinder pressure and NOx output for a bit more power and mpg)
