What is your suspension and tire setup?
Looks like you should be able to dip into 13's if those numbers are on street tires.

5mgte quarter mile 104mph trap
Car 155 on the slips track was hot like extremely hot... July in arizona
The track was very slick they prepped it once at 8pm or so and never again.
First run was reading 146~ kpa peak boost(6.7psi)
Very low timing as well 16 degrees
100mph~ pretty good for stock boost pressure
2nd run was after I shimmed the wastegate hoping for more boost(164 kpa - 9.3psi)
Very low timing 14 degrees at this pressure
3rd run bumped timing a bit 165 kpa(9.5psi)
19 degrees timing
4th run bumped timing 2 degrees more same boost 166 kpa on the log
21 degrees timing
104 trap is decent my guess is the car is making 290~ whp
Really needed to lean it out at 5000+ rpm the afrs were reading mid 10s
50/50 of 91 and sunoco 110
Straight 91 would have been fine but was expecting maybe 12 or 14 psi
Need to buy a MAC valve and just adjust the boost on the ecu.
Also on the way home I raced a newer 5.0 on the freeway
It had an aftermarket exhaust and wheels 6 speed
55-60mph starts which are 3rd and 4th gear pulls we were very close but he would pull 3/4 of a car by the top of 4th gear.
This was on an empty freeway 12:30am. We ran 3 times I was surprised I could even keep up let alone make it a close race
