At least you did improve on your previous best time so that's a plus. You really need some go-fast parts if you want to get into the low 13's or 12's. I'm still waiting for my new go-faster parts but when I do get them I'll be selling my old stuff, MPx & 25% OD, Seiman 60lb. injectors, C&L 80mm MAFS, 85mm TB, MP 3.5" CAI & filter, 255 Walbro HP fuel pump so get your money saved up if your interested. I don't know what I want for the parts yet so don't ask, that's all I can think of at the moment.
