man this is crazy. what did you use to get these times, gtech? i don't trust those so much because it said my grand cherokee with the 4.7, 230 hp 295 tq, ran 60 in 5.8 and quarter in 14.2 with intake and exhaust. i was probably more around 6.5 and 14.7. but those 200 lbs. probably added about 2/1oths to your time, so eve it it was say more around 5.8-6.0, your still looking at 5.6-5.8. but wait, im getting ahead of myself. did you use the gtech? thanks........
