Best motor pass to date has been a 12.40@106.something(can't remember too damn long ago. )

Best nitrous pass was during an 1/8 day. Truck ran 7.40@93mph with a 1.9? sixty foot.(spinning some and had the window switch set at 3500 rpms).

 

my best n/a time with the 5.3 was a 13.4 and my best nitrous pass on a hundred was 12.3. don't remember mph. this is an ecsb

 

12.33 motor 12.17 nos

 

12.1 @ 112 with 50 shot spraying after launch, just couldnt plant

I got the Chevy twin of your truck and went a best of 14.57 on the 5.3, with Catback, AEM intake, Yank TT3000, and Hypertech believe it or not. Same deal with a 100 dry went 13.43 spraying off of a button. With the 6L, converter, AEM intake, and catback only it went a 14.40 and 14.42, and I've only been to the track once.
