I just finished up installing some PRC stage 2.5 heads on my 4.8... Turned out pretty good, nothing extreme like a 6.0 swap but a good gain...
Before

After, i did a little DD to show how my verter drives, all that driving was at really light throttle, when you get heavy into the throttle it goes to 3600-4000, i have no clue what it flashes to now...... Think it is a 2800 like i was told? Oh and notice how the shift extension shortened by 500rpm... The shiftpoints are the same in all the videos, they are set at 6600rpm, but i am thinking of upping it to 6800rpm...
