2017 camaro zl1 power issue
 

Hi everyone I have a 2017 camaro zl1 i will do the best to explain the problems I’m having.I have been having some issues with under throttle it cuts out and holds you back.about a week ago I was doing a pull and it completely cut out and started running horrible I took it to the dealer and they found one of the spark plugs tips broke off and went into the cylinder they put a camera down and claim it caused no damage they replaced plugs wires change oil they replaced/fixed a few burnt wires and the O2 sensors.also the packing in the catalytic converters came lose and was found in my back muffler.so now under heavy throttle it cuts out and holds you back and almost makes a little tick keep in mind the car runs completely fine Idling and driving.just under throttle they claim it’s my fule pump going out any help would be appreciated!thanks ahead of time!I forgot to mention their are a few mods borla exhaust smaller pulley and intake and tune

Sounds like a fuel issue. Either the fuel pump is dying or the filter is almost completely clogged.
