    Loving these rockers. At 70mph I can punch it and downshift into 3rd and it'll pull all the way the gov at 110. Lost the HV3 due to a hasty install which caused a coolant leak from the throttle body....

    Funny thing is I'm not having any symptoms of a bad MAP sensor or intake leaks... It makes me wonder if the change in airflow along with the much cooler air is throwing the readings out of wack.

    I'm using the stock valvetrain. According to ZZP it won't cause any damage unless I can find a way to rev the motor above 6k. I may go with springs at a later time and raise shift points/rev limiter...

    According to ZZP if I install the HV3 insert along with my ER Rockers and port and polish my throttle body it'll give me more gains than a cam.

    The ZZP tune won't work on 06 and newer 3800 pcms, and I'm not a fan of getting rid of the drive by wire system on the series 3 motors, plus the rods on the N/A are quite a bit thinner than the s/c...
