Two predator questions.

[Ey34nEy3]

I hope I'm posting this in the right forum..

My first question is I just went to my local muffler shop and had them put
on two Flowmaster 40's and removed the resonator, now will modifying my exhaust in this manor mess with my Predator 91 octane performance tune?

And second right now I'm running the 91 octane tune, where I live all the have is 92 octane for premium. After talking with a buddy he said it would be alright to run 92 on the 91 tune, but to not use 92 on the 93 tune. Just want to make sure that is alright to do.

Still a newbie when it comes to cars and tuners, I know my basics and just
want to make sure I'm not messing anything up yet. Thanks.

youre spot on.
no need to touch the tune with just a catback exhaust mod. headers... then yea might be good to tweak the tune, but not just a muffler.

many people run the 91 octane tune witih 93 octane gas just to make sure they dont face ANY spark knock if the gas isnt 100% the best quality.
so youre doing the best by putting in 92, with the 91 tune.

keep on rolling dude
