I like to run springs only in my racetruck. I get tired of messing with controllers.
If I do use one, it's very simple. It's the cheap turbosmart controller that bleeds off the hose.

You used c16, but mixed it with alot of pump gas. I run about 7 gallons of 110 with about 3 gallons of 93.

I thought is was his tune and over boost that caused the failure?

That's why I always build FI tunes so if it over boost or get into a part of the table that isn't tuned for, it goes pig rich and pulls a ton of timing. I know my truck will instantly pull about 10* of timing if I go over 16psi, and my VE tables look like valleys with the tuned part being the bottoms and everything else is a far bit higher just in case something like what happened to him happens. I can't afford new motors every other week
