Well guys...Got some good news and some ok news. First off want to say the truck did damn good today, took about 10 hits at 600+ out to 150-160 MPH in 3rd gear pulls and didn't give me a single issue.
However, bad news is dyno could not load the truck to get her passed 16.5PSI. Maxed the boost controller out, thats all it would go. Street I see 20-21. Any who, did get some good tuning in and truck made a solid 627HP/650TQ at 16.5 psi thru the big dog 4l80.
More good news, nitrous doesn't care about load...
That said, i'm uploading the video now and graph. Any one know of the current highest HP 4.8l car/truck?

Shiiit, what kind of dyno? Looks like you picked up a decent bit of torque over your last dyno with only a small boost increase. Lets see the nitrous numbers 
Pretty sure you've got the 4.8 power crown...for now!
