So...Im getting ready for tune/turbo install, gonna put some 91 in my tank instead of 93 and guess what?

I cant find 91 at any of the local stations. The lowest they go is 92 around here... I cant believe that this is a problem for me lol.

Oh i been running 93 for no reason cept that egr is deleted and just wanna make sure i didnt have a problem.

Why the crap would you be running 93 NA and now your going boost want to go to lower octane

Stay with 93 if you can get it and be safer

^^^ Agreed, why would you bother looking for 91? I'm confused here, I run 94 in my blown car when I can find it.. I"ll take all I can get ( maybe even a splash of race fuel now and again).

Are you trying to tune to 91? I'm so confused.[idea]

Have to agree with Tom here, Only run less than 93 if youre running stock internals and dont have any major engine mods (turbo, nitrous, SC).

If for no other reason, it makes more power than lower octane.
