occasional throttle interruption with h&s hot setting

i have a minimaxx with the h&s hot setting installed and sometimes if i go full throttle from a stop, around 2nd or 3rd gear it will act like traction control or something, the truck will completely get off throttle for a second then get back on it. its not defueling, and no check engine lights

What is your Pyro defuel set at. The first couple WOT runs on hot defueled when I had the Pyro defuel set to 1450. I raised it to 1600 and it won't defuel on 0-80 runs now. The defuel happens fast and if your not watching your minimaxx closely you won't catch it. It will bounce between the hot setting and one of the lower settings until you let off. If this doesn't work email Casey or Bently. I've never had to wait more than a few hours for a response. Their customer service is very good.

If it is happening right at a shift... If the transmission does not shift right or quick enough, it will defuel for a second to shift. Its as quick as turning a light on and off. My truck has done it a few times when I didn't let it learn a big tune long enough before running it full throttle.

My truck does the same thing. It will mess up shifting 3 to 4 when 75%- 100% throttle, but only when starting at a rolling start. I am running the Hot Damn tune, and have my EGT defuel turned off. It does not say its defueling when this happens. Maybe we can get some insight from Bentley or Casey on this.
