Default Acceleration delay

I no this was touched on a while back but was wondering if anyone has fixed this crap, you no want take the gas then takes off like a bat out of hell,my 07 has done it since i've had it, i guess about three years now, just put on a new throttle body and checked the tune and still does it, i can live with it but want to sell the truck and this is going to be a problem, it doesn't do it all the time usually when i pull out in front of some one lol. THANKS!

Check your ETC rate limit under the engine tab. Stock is .10 Set it to 1.0

If you're talking about the irriting delay between being totally off the throttle and getting back hard on the throttle, I read that it is in GM's tune somewhere. I hate it too, but I read that it's to ease the shocks to the driveline. Ask Google, there are lots of discussions but it's out there.

Here's one discussion:

Thanks for all the replies, it's a little different than that though, you can be going down the road doing 65 and it will just stop taking the gas and it might do it for a second or for a couple of miles, then all of a sudden it will just act normal again, I can pat the gas sometimes and seems like it does a little better, and it doesn't do it all the time it may be a week before it does it again, It's like its loosing signal to the throttle body, no check engine light or anything, crazy, THANKS!
