Sounds like you need to delete the PPRV in the fuel tank, a common issue on these cars when modded and shifted hard at redline. Plenty of threads on it here if you search "pprv delete"

If it's a new development I would datalog and see what the fuel pressure is doing. The PPRV delete won't fix a failing pump.

Most likely pprv. I had it happen over and over two weeks ago, frustrating.
Ran into my tuner, mentioned it to him and he did a touch up. Will give that a shot, otherwise yanking the tank.

Well I already did the pprv delete and I have ford gt fuel pumps in there as well so I know it aint those because its still does it at wide open throttle but just cruising its fine idle just fine but wot just like it losses power i have a video to show yall from the drag strip last Friday night. The video to show you what it does and lol no I didnt miss third or forth thats what I mean hiccups.

Did you log the run? If your pumps are good your tuner should be able to tune it out.

I didnt but I guess I need to put my sct x4 and watch it next time
