Default Bog off the line

What would cause a slight bog off the line? When launching at about 2400 rpms( holding the brake and gas ) and then mashing the gas, I get this. It feels like max power is not being applied. After about 1 to 2 seconds there is a surge in power and then the car pulls hard through all gears.

In theory, I have disabled Torque Management via LS1Edit.

Not enough gear will usually bog a car when it hooks at the track. Also not giving it enough RPMs to compensate for the hook.

Tell us what kind of gears,size tires, mods. U might be running to big of a tire.

Here is some info on my setup:

- 26x11.5x16 ET Streets
- HD built 4L60E
- 3800 TC
- 3.90:1 gears
- 383 stroker making about 430 rwhp
- Original programming by MMS;
Torque management removed and other changes via LS1Edit
I also disabled Abuse Mode; torque and timing reduction

Power braking I can only get the rpms up to about 2400 to 2600 before I start to creep forward. This was about the same level I could go with the 3200 TC before I got it rebuilt to 3800.

I should also add is that it is not really like a bog, a dip in rpms. It is more like max power is not being applied. The rpms and mph increase moderately until about 4000ish rpms then the car takes off

Well, that just sounds like a peaky torque curve.
The right converter would flatten it out (effective
at the rear wheels) and put you into the powerband.

That sounds just f*cking wonderfull. I had a 3200 Vig with upgraded clutches to handle a big nitrous shot and the shop I use to use recommend a upgrade the stall to 3800. So are you saying that I have a $1300 paper weight
