got to put "Betty" on the dyno today to tune more than get numbers, but the torqe this 5.3 put down was very nice, so I thought I would share. I can't get a good pic, nor do I have a scanner. I have a n/a run and 2 n2o runs. Its a dave's nitrous express truck plate jetted 52/35 and I took plug readings and AFR. It made 407hp/534tq and 11.6 to 11.2 afr. it made over 500ft/lbs from 3000 to 4300. I could pick up a little more by going a little leaner and trying for that 11.8 target, but I feel safe with the way it is. oh and these numbers were unlocked in 3rd gear.
