Please suggest, 3rd Gen Does ECU flash really work

[ravipasupuleti]

Hello Everyone,
Thank you so much for all your support here . All of you inspired me in many ways. I absolutely love my 2013 Yaris hatch auto and want to enjoy more of it. I have done a bunch of mods. I am looking for options to increase low end torque (stop sign to 40 feels sluggish ) i reached out to a guy in PR and he claims can do an ECU flash for stock setup. Does an ECU flash really help ? any idea on approx gains (if any) with stock setup.



Here are my mods done so far. Please suggest any mods that might help improve the low end torque.

1. 1ZZ Throttle body swap. ( car is surely peppy after this ).
2. Tanabe Medalion Touring Exhaust Axle-Back
3. Android radio install with back and front camera.
4. Auto dimming rear view mirror
5. Side mirror turn signals install.
6. Headlights assembly swap with 5K bulbs.
7. allow wheels.
8. Tach Install.
9. Under dash led strips, Shiftknob swap.
10. center console arm rest install.
