i just did a data log on my stock camaro that was tuned by lg. I was looking at my degree's of ignition and it was showing 41 degrees of time. that seems alot to me for it being a stock car. whats your input?

yah it doing that at low rpm cruise and wot but at idle it is down to 21* . Why do they put so much into it?

Light load lean cruising conditions cause light cylinder pressures. Less pressure=slower burn. Slower burn=needs more timing to obtain ideal peak cylinder pressure timing. Short story is that you get better cruising fuel economy. It shouldn't be anywhere near that at WOT.

24-30 depending on vehicle and mods
