It works fine, used the stock gze Ecu with 13 psi on a ae92 afm setup for years. Runs abit boggish down low due to over fueling but as revs go up leans out and rips hard.
Restricted to around 140-150 kw due to afm or ae101 boost cut on Ecu , afm doesn't have the boost cut so it's more workable. It's good enuff but nothing beats standalone on a 4agte
