the advantage is the ability to run more boost, timing and leaner afr
all of which will usually produce more power
99.5% of the tunes i do, include a 91 and a 95 oct map
On an sti i usually see an increase of 20-30 ft lbs and 15-20 whp
you can mix 93 and 109 to get a mixture you can reproduce with 104 or 100 and 93.
Lets say you want a 100 oct tune
5 gal of 93 + 4 gal of 109 = 100 oct
2 gal 93 + 4 gal 104 = 100 oct
and so on and so forth.
Does that help?
