Studder when coming back down from launch

Ok,I assume you are talking a Holley. If so ,you have rear jet extenders, that's good. The next step is to check if you have a "whistle" in the front block.That is a plastic tube that will keep the fuel from sloshing thru the vent slot at the top of the metering block.Install one in it's original length-DO NOT shorten it for a car that leaves with the wheels up! Hope this helps.
