Check out this Ignition Timing table
 

I made a spreadsheet on microsoft excel to show how my timing reacts throughout rpm and manifold pressure changes. My LTX-8s came with real agressive timing from microtech, so I toned it down some. Attached is a screen shot of my timing, I was hoping those of you that know timing can take a look and see if this is safe for california pump gas (91 octane) up to 13psi or so.
If anyone want the real program to play around with their numbers just pm me a email address to send it to.
