I just pulled my 1jz (turbo) back to 15.87:1 from 15.3:1, it seems to show positive results, ice yet to try my new ignition map with it (couple degrees more) and hopefully see more benefit. Hopefully ive yet to reach the cross over point where im no longer gaining ground, still wanna see 40 mpg one day
