Right on though, Fuse. Yeah, I've heard some folks (assuming they're seeing 10psi, like me) have their retard rate anywhere between .8 to 1.25-ish per psi. I gotta ask, what max boost you runnin'? And what's your base timing down to at WOT?

As for my fuel setup, I'm pretty confident that my FMU is on point as far as rise rate goes. Same also goes for my fp's settings, both idle and max. Back in the day, it has been universally agreed that static pressures on FMU should be set at 36 to 38 psi. That takes care of max fp's @ WOT resulting in 68 to 72 psi max. Keep in mind that these stats are specifically to my setup (8psi pulley, RC 310's, Cartech FMU set to 36-38 static, AEM regulator mounted at fuel rail set to 32-34 static, HO fuel pump).

But I think you're right, to a certain extent. I might lower my baseline timing by one degree. The upside of doing this, to my understanding, is that I can lower my overall operating temps because retarding and advancing timing increases engine temps. It'll probably help my 1 or 2 degree knock retard at max boost. But the obvious downside is the slight loss of power across the power band.
