Cobalt SS Advance Timing?

[Rush]

I'm trying to get a feel for what is consider good advance timing on a supercharged Cobalt SS. I always thought the more advance timing the better, but at WOT I'm only seeing 19 degrees. A friend of mine with a turbocharged car says he has less than that on his and that on a boosted engine you don't need much timing advance. So I'm looking to see what other people think is normal advance timing for under load conditions, not normal driving conditions (I see 45 degrees under normal driving on mine)?

I know using meth injection Area47 hit 25 under WOT and stated any more timing and the car would lose power. So if you have meth start at 21 and work your way up looking for knock. Just don't go over 25.

Nope just pump gas, with an octane booster added every now and then.

Max timing is 24.5* but 19 is still a respectable amount on pump gas.
