the timing increase is not an earth shattering mod, i noticed better low end response and better overall mileage. another way to increase more important timing is to have a fpr and bump up the pressure, then use an afc/emanage/etc to back the fuel out.

In Central Jersey, they only have 93 as best option for fuel. Should I have 20 degrees or 17 done on my 02 SE? And how much mileage increase would I see? Also, anyone know any dealerships in Central Jersey who does the advance?

I will try the second suggestion later. By how many points is the suggested bump to the fuel pressure? Thanks again for the help
is 100%?
just like my intraweb spelling.

makes sense to me 
Octane is an alkane with the chemical formula C8H18. It has 18 isomers.
One of the isomers, 2,2,4-trimethylpentane or isooctane, is of major importance, as it has been selected as the 100 point on the octane rating scale, with n-heptane as the zero point. Octane ratings are ratings used to represent the anti-knock performance of petroleum-based fuels (octane is less likely to prematurely combust under pressure than heptane), given as the percentage of 2,2,4-trimethylpentane in an 2,2,4-trimethylpentane / n-heptane mixture that would have the same performance. It is an important constituent of gasoline.
Octane has 18 isomers :
* Octane (n-octane)
* 2-Methylheptane
* 3-Methylheptane
* 4-Methylheptane
* 3-Ethylhexane
* 2,2-Dimethylhexane
* 2,3-Dimethylhexane
* 2,4-Dimethylhexane
* 2,5-Dimethylhexane
* 3,3-Dimethylhexane
* 3,4-Dimethylhexane
* 2-Methyl-3-ethylpentane
* 3-Methyl-3-ethylpentane
* 2,2,3-Trimethylpentane
* 2,2,4-Trimethylpentane (isooctane)
* 2,3,3-Trimethylpentane
* 2,3,4-Trimethylpentane
* 2,2,3,3-***ramethylbutane
