Hey guys I have a 6.0L LQ4 w/ 9.5:1 compression. Im running an aftercooled vortech v2-sq trim at 10 psi with a cam motion 223/229 blower grind. Im starting to tune the timing tables with HPTuners, right now im running about 10 degrees at WOT and it feels pretty good, however I was wondering what the max timing I will be able to run is going to be before I start recieving knock retard. Is there any rule of thumb as far as how much timing to add and how much to back off once you find the max?

Any suggestions or advice is appreciated.

Thanks,
Joseph.

Pump gas? 15 even would be real safe I bet. Then work up from there.

I'm running about 9psi on an lq4. I could do 20* on 93 octane. I've added meth injection and have made it to 22*.
