RE: Track Times & Dyno #'s - 4.0L
Greg, I had the same problem untill I changed my fuel filter (18$), plugs and switched to mobil 1. I instantly dropped 3 tenths, then 2 more(after some lightening and mod.). All the mods in the word didn't get my car going untill the base was working properly. Try those things and drop your tire pressure to 30 rear and max inflation on the fronts. I'll bet you a six pack of your favorite you go faster.
