Whoever did the advanced timing on their VG, did you run into any problems yet? Also did anyone do the ignition timing?

 

I advanced mine to -30deg, but most people only go to about 20 or so.. mine severely knocked when it was above 80deg outside and I used less than 93 octane.
I don't recommend going that high. I was jsut too lazy to change it (since it takes all of 45 seconds).

try about 20 deg or so.
