Sportside 5.3
this was the first time ever that i've been to a dyno, didnt do everything as i thought out before,
The cam was installed dot to dot, its on a 112, the exhaust when i had my catback put on was 2 1/2, the ypipe (when it was one) tubing is stock size, just had some 2 1/2 pipes welded in place of cats,
i didnt tune on the dyno, (didnt want to break the bank) just wanted my a/f safe. timing is at 28, next time i go i will probably make a couple files before i leave to dyno.

What kinda tune are you running? SD w/ MAF?
Now, that's impressive. Cut that down to a 1.7 or 1.8 and you'll be edging twelves more than likely.
You should try a bigger cam, or head work. The 220 .55X TR lobe isn't that big... What did you see peak hp @ about 6100? 6150? or did you hit 6200?
I can probably find that lobe.... it might be priority though

yea, i think 12.9 should be feasable with some et streets, and weight reduction,
i took off my speaker box , spare, factory hitch, tailgate and they weighed in at 220 pounds, that is with a walmart scale, dont know how accurate it is.
my tune is not sd, i might work on that later on, still need to read more, just using the regular dope style ifr tuning with pe, timing, other minor changes that trucks lack, and the idle tuning
if it dont hit 12's next winter, a 224r will be something i may look at, headwork is just to expensive for the gain i might get, 6.0/w headwork is more like it..

The torque peaks mainly.
