Can some one please give me a little info on a starting point of how much more timing i can run at a given boost pressure from 94 to 110oct fuel. I understand i will have to finish the tune but i just do not wanna have to keep adding 1 degree at at time if i make a jump of 5 or X value right off the bat. Thanks in advance. I have searched but with no luck.

 

I typically buy 5 gallons of c16 and start bumping up the timing little by little even with 117 octane rather than making big moves. However, as long as you're watching the knock you should be able to make bigger leaps. Trap speed should give you a good idea about when to stop since they'll start falling off when you've gone too far if you aren't already knocking.
