Apexi S-AFC Neo vs Dastek Unichip Q for Myvi

[brandylau]

Hi Sifu sifu out there,
Currently my fuel consumption is high and after reviewing my dyno graph my air/fuel ratio for an NA car is fluctuating from 12:1 to 10+:1 ratio which is running too rich for an NA auto myvi 1.3

Was wondering if anyone could suggest me on either Apexi S-Afc neo or Dastek unichip Q as an mod to tune my air/fuel ratio. The pros and cons of this two products on our myvi.
This is because I was offered a good price for a set of used Unichip Q and was wondering if I should get it.
Thank you so much if someone can help me out.

Brandy : I like how you think. A/F not running right you install a piggyback. Hehehe.. good way to get started modding.

But like what Pomen_GTR said - it's likely your car has some inherent problems already so easier to just change the faulty problem and go with that.
