simple... for those of you that have tunes for 91, 93 octane, do you find that the HP/MPG bonuses are worth the extra .15-30 cents a gallon on gas? or are those out there better off running a more conservative tune on 87?

it is worth it if you have the mods that require it like cams or f/i. helps cut down on detonation.

who know.....but its only about 2-2.5 $ more a fill up for me to have the predator tune

and when i got the tune/cai i could definatly feel a difference in accel

when my car still had the stock 4.6 romeo block, the first thing i got was a diablo tuner, it made my car run smoother and i got better gas milege, at least when i wasent driving it harder because of the increased throttle responce. those things rule

If you are going to run a conservative tune for 87 octane there is no reason to buy a flash tuner, simply stay with your stock tune.

if you get a diablo tune.. max out the spark advance and get 93oct gas.. otherwise just keep stock tune.
