    Any regrets???
    It was originally a 3200 but my car didn't care for it so they tightened it up for me. Now it works nicely.

    I love my 3600. I get 16/22 and that is with the cam. On the highway, it just feels like an extra shift when the TCC locks.

    You will need tires, there is no way around it. It wasn't even fun going to the track without tires with the stall.

    You can say that again Robert.

    * Does anyone else's RPMs "bounce" when the car is coasting between 45mph - 70 mph? Is this the torque converter unlocking?

    I'll be going like 65mph and then take my foot off the gas, and the RPMs will kind of bounce from 2500rpms to 1000rpms then back up and down....

    Is this normal?

    Mine use to do that before I tuned it out. Zero lock up issues, zero RPM bouncing, good gas mileage. I have said this several times but the stall was harder to tune then the damn cam was. It drives like stock now, except when you hammer it.

    I should see about getting it re-tunned to get that RPM bounce tuned out....

    Yes you should. I would bring that back to your tuner real quick.
