    4.8 on the dyno

    Truck
    2004 SCSB
    4.8 150k
    4l60 transgo shift kit and vette servo
    TR224
    K&N CAI
    Pacesetters
    Cat delete
    Dynomax internal X Pipe dual 3" in dual 3" out
    4.56 motive gears spooled
    33" tires
    yank 4000 stall


    The tune was done at Synergy Motorsports in Fremont CA
    about 70 degrees outside

    It made:
    319.8 RWHP
    301.2 RWTQ

    This was on a dynapac.

    Im extremely happy with the truck, and cant wait to see what it does at the track.

    Let me know what you think.

    There is no perfect dyno. I'm just sayin what the sheet said. There are many outrageous numbers out there and I'm not under the impression mine is to far from the truth.

    Those numbers are believable for that setup though. To me anyway, maybe a smidge high, but within the realm of possibility. Point is, it'd be a fun truck in the sand.

    A 224 is going to gain you near 80-100 rwhp?

    Should be more along lines of 270rwhp

    Intake,cam,cat delete,long tubes, and a good tune can't make 80 rwhp?

    There is a thread on here that does 100 on a 5.3 with a smaller cam from Nelson. Are ou saying he is BSing too?
