I'm not sure the afr. My tires were set at 20psi for that run. I'm sure I would have hit 115 with a better 60ft no?

No the 60 ft wouldn't change the MPH that much. Without knowing certain things it's hard to say why it's trapping so low. Could be a combination of things as well. That's why I started by asking about the tune

I gotcha I'll try to find out. I did talk with the tuner today he seems to think some more suspension mods would help. I already have upgraded sway bars panhard bar lower control arms and qa1 rear shocks. What else could I do? All those mods are non adjustable .the thing is I want to also autocross the car so I don't want to lose handling features. I currently race it at a oval track

Lack of suspension mods have very little to do with the MPH that you're experiencing here. To be very honest I'd get this worked out before moving on to something else

I agree with HCI2000SS.

Converter and full exhaust only cars usually trap 108-112 mph.

With automatics the stock suspension will carry you a long way. I'm 1.5x with just the stock torque arm relocated off the tail shaft.
