    i just loaded the tune and goind upward coasting to stop at the corner of the steet the truck trying to correct the idle underspeed make a hard bump in the transmission. then zeroed the 'coast step decrement and idle step decr' in the tab IDLE-RPM-FOLLOWER in the 2nd log you can see the truck dies 2 times

    Here is the log from the last file (idle4), then played with torque follower, and integral airflow. the problems are the truck is the oscilating idle in park, and then from park to drive. and in a downhill the truck feels accelerated to much even make a shift . in park is also a little accelerated.

    What mechanical issues recommed to check?, because this camshaft is't to aggressive and it's giving more problems than a TS magic stick3 .
    Also how can compensate the lack of torque in the low end with the stock stall?
    thanks
