Sounds like you have a restricted or plugged cat converter. jack up climb under loosen all 6 nuts for cross over pipe 3 on each sideshake exahust until it is free from manifolds then test drive it will be loud. But you only have to go far enough to see if it still boggs down

have a 2000 chevy and every time i stop then give it gas it bogs down and it even back fired.ive checked the vacumm line with a pressure and its reading fine until i give it gas then it backs down a lil bit.ive done a complete tune up,sparks,wires,fuelfilter,k n air filter.its just weird cuz theres no check engine light on
