Breaking up under load!
Hi everyone. I've been having an issue with the car breaking up. Only happens after the first couple miles after a cold start and at low rpms when I give it gas, not WOT just any kind "excessive" throttle to get up to speed. If I hit the throttle hard it almost pauses then hits hard. After I drive a few miles and car gets to temp it stops doing it. Any ideas what it could be? Thank you

Sounds like your tuner didn't do any street tuning in the driveability area. Should make sure they get some logs of you idling from cold to fully warm and cold start driving to fully warm. Do you have the ability to log?

Do you at least have WB02 to watch real time, bet you are way off on fueling at cold temps

check plug wires and plugs first...most likely something simple like that
