On 12.5-13psi on my failsafe 92 map i still have a decent amount of timing although I’m probably right at that limit where more boost is pointless maybe even already a little beyond the limit, i would need to dyno comparison to know for sure. With my WMI i probably have a little bit more headroom left as i can safely run a bit more timing and obviously cooler IAT helps a lot too.
If you max out timing in ideal conditions then won’t it be risky in less than ideal conditions like on a track or on a hot day because then the engine has no wiggle room to adjust timing?
