This started a few nights ago.

It does not make the sound on the highway.
It does not make the sound from a standstill start.
No modifications to intake or exhaust.
No trouble lights,no liquids under or around the motor or car.
Car feels to be running great.

Whats going on? When I am on surface streets doing anywhere from 20mph to 35 mph and I either give it half or full throttle there is a strange noise. The noise is hard to put in spelling but its kind of a Roooomp sound. It only lasts a second.

 

Have you seen this? I don't know if the noise is close to yours?

That sounds like it could be the problem. So its a TSB does that mean the dealer soaks up the cost?

 

No. TSB - Technical Service Bulletin. Just gives the mechanic's a heads up on known problems.
If it's too bad then it becomes a recall if safety or other things are involved.

+1. Can sound like a 'hoot' noise.

 

I guess its the brand then. I know that my 2005 Dodge Magnum had a lot of TSB's and they were all performed at dealer cost even when I was out of warranty.
