engine wont lean out!!!!

[Coder24]

ok I have a greddy emanage and I cannot get the car to lean out. Also my check engine light keeps flashing on and off after the install. Basically the car is running dog rich and wont lean out...Its dumping it into the exhaust it seems...im getting fed up. and im also getting idle surge like an sob... I have 2g pistons in my 6 bolt 91. stock turbo with a fmic.

You're probably knocking, timing should be set to the stock 2G values as a baseline to start from when using the higher compression 2G pistons, and please do a boost leak test if you haven't already.

Why don't you see what your engine is trying to tell you
ECU Code Checking
then do a boost leak.

Ill have to check this... Like it runs Fine but with a little surge and a little rich. but when I goto Restart it...it doesnt want to for about ten minutes...the emanage is Shooting me a Red light under active(which means error)
