14 degrees of peak timing is a little low. it must be a real conservative chip

We really can't tell anything without seeing what's going. Could you post up a log of some sort?:thumb:

try and pull to 7k+ 14* is fairly low, with no knock there is something you can turn up to crank more out of it, boost, timing , lean it out a little. (if you have the means), the o2 at .76 im not sure what that means. but aem wb shows it at 14:1 on a 0-1v but that obviously cant be right. long story short dont even pay attention to o2.. unless you have a large leak somewhere before the sensor.

That o2v on a good sensor is between 11.0:1, and 11.5:1. Timing does seem low. I usually shoot for 18* at 7k rpm's, with upped boost. 4* of timing in that range can be a good amount of power left on the table.
