Your first problem is your mileage - your just starting to break-in at 2000k. My 2001 WOKE UP at around 2500-3000 miles. Also try lowering your tire pressure to 20psi left rear - 18-19psi right rear. You gotta peddle these trucks at the starting line or you'll spin like mad which = drastically reduced ET. I'm installing a few more mods before I run at the track - but with my two nephews (an extra 315LBS!!)on board & a G-Tech Pro, we ran consistant 12.8s with about ten feet of tire spin and a best 0-60 of 4.7 secs! Remove the two lead weights from the front seat and we're talking 12.6 or better.
