How much more timing advance???

[vic@eurosport]

Hey guys,

I have a 95 GTI VR6T making 273whp.

I believe I'm running about 15-16 degrees total ignition advance and the car is running great, but any further advance in timing will create some pinging.

Just wondering if there is a rule of thumb for ignition advance increasement with the WI.

How much further are most people able to advance timing after the WI installation?

Thanks,
Vic
