Livernois makes great stuff, don't get me wrong, their tunes are super safe and reliable. But I prefer the flexibility of 5 Star too. You can get multiple tunes (tow, daily, performance) and switch them out easily depending on what you're doing that weekend.

My old man taught me to tighten scope screws until they just stop, then give a tiny nudge. Never had a scope slip in 20 years.

Isn't it always the same with any risky job? The deeper you go, the smaller the margin for error gets with everything. That 15% jump just shows how fast the rules change past a certain point.
