Default New Dyno #'s with new cam, VID included
Went up to the dyno today with some other guys, BTW nice to meet some of yall.

Previous setup was a 220/220 .56X/.56X @114+4 and LS6 Intake
I put down 303/300 power dropping off at 5500 ... The graph was done in MPH, but from the logs I added in RPM. 3rd gear, i believe the TC was unlocked.




New setup, 222/224 .56X/.56X @ 112+2, truck intake
I put down 316/287, The power started dropping off at 6300 ... 3rd gear TC locked




Vids








I don't know why i lost TQ, maybe something in the tuning, i dunno, but the truck runs alot stronger and I gained .2 in the 1/8th with the new setup... These were also done on different dynos...

The log is also attached ... Timing was a little bit higher than i expected...



Next up are a set of PRC 5.3 58cc 2.5 stage heads ....

Nothing compared to your 6.0, the way you left me on the highway was kinda funny and sad at the same time...
