ok well i finally installed the 93 octane tune with the predator on friday after trying out the 89 octane tune first and honestly did not notice much difference

if anything i felt the 89 octane tune a bit more better than the 93 tune


before i changed to the 93 tune i did increase the shift firmness and adjusted the settings for my 22s while still on the 89 tune and did notice the shift firmness but does changing the tire settings really make any difference or help at all? i also adjusted the shift firmness and tire settings again once i changed to the 93 tune..
