    throttle follower question

    trying to find some info on how to adjust the throttle follower tables the step down and step up tables. i got this issue were around 1000 to 2000 rpm when cruising when i let off it fells like the cruise is on i can see it on the scanner that the etc table slowley goes down takes like 2 to 3 seconds to go down. i dont understand how u adjust the throttle tables do u raise them or lower them . i raised the step down works good for higher rpms but not around 1to2000 rpm. i have taken timing out of the coast down table and out of the timing high and low octane tables but still does it anybody have any ideas.. and its for a 2006 vette g5x2 cam fast intake melrose headers anybody can help

    Throttle plate is free, not gummed up or dirty? Take the MAF off and feel it by hand to see that it snaps shut on it's own.

    I don't rape PE tables cause I don't know what I am doing anyway....

    That's because:

    1. You need to hit the throttle cleaned reset button in the scanner. Considering the fact that you have cleaned the material that coated the inside of your throttle body that the ECM has learned the Airflow values with.

    2. If that doesn't get the job done, reduce the BRAF by 10% until you get it where you want it.

    Check the timing in those areas. If the timing is too high, it can make the car seem to drive itself at closed throttle
