On cars I have tuned there has been 1 broken L26 rod after insane amounts of abuse, and my drag car blew a felpro headgasket this year on 27psi of boost.... maxing out 2 340lph fuel pumps and 110# injectors.... made about 30 passes on one 40 mile trip from detroit and it blew.

My track record is pretty good if all I have to show is a broken $9 headgasket from "bad tuning".
