TQ Help

Here's my problem on my 340 Demon when from a dead stop I hammer it
it's just like a throttle stop bogging it down then it catches and goes good.

and this only happens from a dead stop as from a say 15 mph roll and hammer it it jumps and goes and when it shifts squaks the tires.

so what neeeds tobe done to fix the problem?

and no don't get rid of the TQ.

thanks
