I searched could not find much help. Okay i changed the front o2 sensors to the corvette ones have the eliminators in the back. I have long tubes and no cats. All my problems started when i went to long tubes and x-pipe. I don't know what else to do.

Get the car tuned. Some cars really need a tune after long tubes go on. Also check to make sure all your plug wires are snapped on all the way. May also want to change the the fuel filter and check for vaccum leaks.

Is the car throwing any codes?

I just took my car in for a bad idle. Turns out it was due bad intake gaskets--> vacuum leak

Also, if your throwing a code, check the engine sensor, might have blown, which sends the car in open loop at all times.

the codes it is throwing are p0171 and p0174 which are supposed to be o2 sensor codes i have no idea. Im getting to the point where i wish i had not changed to true dual setup,but..... it sounds so awesome even my Mustang buddies say it sounds good.
