87 vs 93... nearly full bolt-ons

[RoadconeTuning]

ok... im running a stock tune still since the car runs better, it doesnt buck as much and overall just seems to be a better running car over the diablo tune, and ive got longtubes, h-pipe, flows and a JLT cold air... well the car has always seemed to run a TAD smoother on 93 but im curious if the added airflow would be enough to warrant running 93 octane instead of 87... i dont hear any spark knocking or anything... just the usually header ting.

so is it worth running 93 in the car with the boltons i have or would the slower burn rate of the 93 actually cause me to lose a few hp...

I have a custom 93 tune from sniper with my mods and it runs very strong. I have an 87 tune for it too. Honestly i think with the mods you have i'd just keep the 87 in there. I know mine aren't much more but it's up to you. I've had too many experiences with getting bad fuel using 87.

With the stock tune feed it 87 unless it knocks, which you say it doesn't so don't worry about the expensive stuff unless you put the/a tune back on it.

i run 93, only because my timing is set a @15*
