    H/C 5.3 new numbers

    I got my new numbers!!!!!! I am VERY happy with them.

    390rwhp and 366rwtq.

    We were hoping for 350rwhp, but the first pull on a weak tune was 354rwhp and once we got the a/f perfect it hit 390/366.

    Hopefully get to the track in the next couple of weeks, and see what she puts down!

    Dyno sheet below.

    03 ECSB 5.3 N/A, bolt ons, cam, PRC stage 2.5 heads, 8.1 injectors, 2400stall, lakewood traction bars, G80 3.73s, elec fans, Fram boost intake, HPtuners by Ben Sundling, DMH cutout.

    Best 1/8: 8.786 (at 5060lbs)
    Best 1/4: 14.00058 (at 5060lbs)

    390rwhp and 366rwtq (dynojet dyno)
