Sputtering w full throttle

Hi guys I went to QUALCOMM Stadium in California legal 8th mile drag race it was an absolute blast I actually won a trophy for quickest time in my class 8.5 to 9 second 8th mile class averaging around 80 mph

Question:
In 90% of my launches in track mode w non paddle shifting I noticed some sputtering from underneath the car as I started to go down the track in first and second gear as best I can remember, felt like it might be something restricting the exhaust this was for a couple seconds and then disappear as like the car broke through it and was able to flow
Happened on most of my runs not all

I have a full Flowmaster exhaust pipe n stock catalytic converter's w delta 40 flowmaster mufflers

I've had the exhaust for about a month and a half never noticed anything up until about a week ago I did notice that before I went to the track the last few days car still ran great like I said just felt like it was being restricted any thoughts

When my kid gets off my iPhone I can post a video for you guys to possibly hear what I'm talking about stay tuned��

Myself and a-kon have experienced violent shifts only in Track mode from 1st to 2nd. In fact SRT approved a new transmission for him but that did not solve the issue.
Sound similar?

The green one highlighted is for 6.4L. Fuel issue at wot. Kinda sounds like his issue. Just thought I'd throw it out there

Re: Sputtering w full throttle

I didn't need to take it in at the dealership thankfully because I had just about run out of gas at the racetrack that was the problem
Omg such a clown
I was driving around yesterday and I remembered I purposely went there with a quarter tank as advised only problem is I raced like 30 times gas eventually runs out
Oops
Thanks anyway guys
