I have an 04 with 35,000 miles on it now with a SLP catback (LM) and a K&N intake and BBK throttle body, untuned.

On the dyno it put down 331 HP and 325 ft lbs of torque

At the drag strip I went 13.6 at 103.12, with a 2.21 60 ft....so definitely not my best launch ever, but I'm happy with the car so far...its the driver that needs improvement

i got as little as 13.38 bone stock. even accounting for launch you should have had a better trap (104-106). you might want to invest in a GMM shifter. it really helps. good luck

Before I had the maggie I dynoed 321 and ran a 13.1 @ 105... launch it better and your times will drop..

I have hope! I trapped 103.9 on a high 70's day... maybe a low 13 in my near future with a 105-106 on a cool night and a CAI with custom Predator tune!

Yeah I'm still not completely comfortable launching the car and I often wheelhop right now too so I don't launch as hard as I know I can.....but I'm whittling it down slowly, I'm very surprised with the LS1's power output though!!
