    Random Hiccup on VVE Cars

    I've had a couple cars do this now. It almost acts like when you miskey a huge or null value in one cell of a VE table or MAF table. The car will just have a random hiccup where the injectors peg one way or the other.

    Has anyone else had this issue? Where is the bug! LOL.

    Alvin I did some logs for one of your 08 TBSS customers . Guy from CT - On his truck It had some KR, but it had some other very random issue just as you describe. Almost felt like traction control or tq management.

    One thing I did on another 07 TBSS truck I tuned, is I kept the abuse mode at 1 vs 0 like you put it. I also don't max out the the trans input and output tq . I keep it just under the max on the 07-08

    Other thing im not sure of is why did you enable -brake torque managment, Dissable by TPS ?
