Maybe its just me (im running a 2.5l) but I run around 30* of timing up until about 4psi and then taper down slowely from there. Your AFR looks about right you have some dips here and there. Other than that idk what else to say. Make sure there are no boost leaks / header / upipe is wrapped and or high heat coated will help.
