FWIW my tires (305/30/19 Goodyear Supercar3R) 100TW. After 1 day at MSRC, 1 day at ECR and 1 day at COTA. I rotated left and right through those days. The most worn one did 2 rotations on the front right of the car.

Yes, they are fast. It might be that Iāve found they are so fast the car thinks itās crashing on high G corners, thats track mode and button held for all advance track off.
Iāve talked to a few well informed track mustang sources about this, we bounced around the idea of it actually being fuel starvation from the saddle tank, but the next step is to first disable under the hood traction control connector and see how that is.

you can trigger traction control, yes, but if its āhold the button for 8 secondsā off, it shouldnt cut power unless it errors out with dash chime and reboots the system, which can sometimes happen.
Sustained left hand turns can/will fuel starve a GT if its much below half a tank. At a quarter tank, forget it, session is basically over.
so try to keep it above a half tank. The 350s have two pickups to help this, but the GT just has one. You can guess which side of the saddle its on.

See thatās the thing, itās not just the left turns, something doesnāt add up on fuel starvation. Going out on a full tank at ECR, after 2 warm up laps. I hit a flyer, and thereās a couple of right handlers there where I get that loss of power sensation out of the exit.
Iāve talked to a few well known shops, other guys at the track, and we talked about that connector under the hood. The consensus is that traction control is never really fully off, and it can reset during a push lap, pull that plug though and the dash lights up like a Christmas tree. Havenāt tried it on track yet!!
Problem may be a combination of the two issues, and/or something else. and I need a little time to figure it out and trouble shoot it. Some data logging will help me figure it out. Last track day was COTA, and I wasnāt about to start experimenting there.

The connector does work. I usually donāt yank the connector because I donāt get a lot of fault restarts. I have seen them a bunch of times in the thousand or so laps Iāve done.
fUll TC error restarts will reset the traction control to default settings a couple sec after you drove over whatever confused the TC computer into giving up and rebooting, and they do ping messages to the dash but you can be forgiven for not noticing if youāre driving on track. After the reset, the nannies are back on in thefull power nibbling glory.
if the TC is full off via the toggle, and it hasnt rebooted, and youāre still getting power cuts, then its something else. The TC power cuts can be abrupt, but if it feels like you ran out of gas for a moment in a left turn, the fuel tank feed is a candidate.
my car would also dump a bunch of oil into the pcv system in specific sections of track, but I think that was an issue specific to the ā16 valve cover baffle designs. The smoke screen out the tailpipes could be seen from space.
