Gearing difference?

[K & S]

I am new to the forum and have questions about 1/4 mile results with different rear gear ratios. I am running a 2015 GT Automatic with a Roush stage 2 blower and a VMP tune and 3.55 gearing. I have run as low as 11.33 but average @ 11.5's. I am wondering what difference 3.73's would make in 60' and 1/4 mile times?

I dont have any real data to back up any time difference but I changed from 3:55 to 3:73 on mine and seat of pants the car feels quicker. Prior to the gear change I never thought the car had as much power as advertised. I use mine as a track day car for road race events not drag racing but I was able to shave a little time off my lap times with the gear change.
