I have a '95 5.0 with a Vortech S-trim S/C running 8 p.s.i. I have 30 lb. injectors, FMU, Better fuel pump, Aluminum radiator, air intake, full exhaust and a 70mm throttle body. All on a stock block with stock H/C/I and all without a tune. I am deffinitely getting a tune as the next thing im doing because it'll help me out alot more. But with my setup....Vortech with small supporting mods, I ran a 12.8 in the 1/4 and had a 1.9 60' with street tires. (And I was shifting pretty easy) I say got with the supercharger, get a good tune, 30 lb. injectors and later on get the H/C/I.
