FYI, I went 13.4 @ 102 back in early 08 with pump gas, street tires, full int. w/ tire & jack, 3.4", XP, Headers, Base DHP tune with raised shift points and the P0300 code turned off, stock TB, Ported S/C, Stock trans, 3" FWI, MSD Wires/Coils/AL103's, 160*, with a 2.05 60'. Probably could have hit 12's with a ported TB, custom tune, higher octane and a 3.2"...never have gone back since though...what made me mad is I didn't run much faster...I had the same mods but instead of the cam/headers...I had 1.84 Rollers and PEM's and a 3" DP...went 13.85 @ 99...with a 1.89 60'...driver mod makes a lot of it.
