    4L60E Trans tune anyone good with these setups? If someone could glance at my tune ?

    Hey guys 4.8 in a 2010 RCLB with a edelbrock SC its a tvs2300 and i have all the sonnax parts minus clutches and was wondering if anyone with experience could take a glance at my tune and give me any pointers on what settings i need to change . I find it dog sometimes on a dig and some times it lights the tires up.

    You can stand to get into PE sooner. I see a couple places were you are in boost but not in PE. Lower the enable throttle to something very low like 2 %. From that point on it should have PE when MAP is higher than 90 kPa that you've already set.

    The VVE hasn't been tuned and is missing or has rough data in boost specifically where you are at on a heavy launch. Read about VVE tuning. Even if you re enable the MAF it makes a big differences especially in transients/idle/etc. This will likely help the bit of lean you have when you start the pull
