progress update 140-160

10 is what you would start at as a base, because that is what's recommended by the factory. Being a b20b, premium will probably be required, but specifically, where are you located, what are the octane ratings over there? Premium for me(in Oregon) is only 91, while regular has a rating of 87. But I know someone in Texas and they have better gas there.

Generally speaking, the b20b will require Premium gas wherever you are.

And as to the 10 deg, BTDC, Use that as a starting point, and then advance in little increments (2 deg or so) and take it out for a hard drive(some people say about 30 or 40mph in 4th gear, then floor it) and listen for any detonation/pinging. Keep advancing until you hear some, and then back off a little bit(2 degrees or so) and call it good.

This is what i've gathered so far, and any confirmation on this from someone with more experience would be appreciated. Thanks guys!

And good luck Greg!
