What is a safe FI tune? I keep reading how many are pushing stock blocks over 600 rwhp and lasting for some time. What everyone keeps saying is "its in the tune". Aside from keeping the air fuel ratio fat and low timing what else is there? Am I missing something?

No thats about all a safe tune is..keeping timing down and keeping afr not too lean. Checking scanner like a hawk for knock retard. Using decent gas or keeping boost low enough. I would stick to 8psi personally on stock block. I might go 10psi if you have lowered compression with heads. And have seen the results of more so if you can't afford a new engine don't crank it up. If you can well take your chances.
Better as safe 500rwhp than a short lived 600rwhp. And 500rwhp is still plenty on the street!
