Default not running right

Hi guy's

Iv currently put my turbo set up on my 92 1.6 mx5 eunos.

Set up
Td04 turbo
326cc Gray tops injectors
255 walbro
Aem uego wideband
Greddy emanage ultimate
Running standard lamda as narrow band
3 bar map sensor
Older guy 02 clamp

The problem I'm having is the car is sitting at 2k rpm and running lean 17+ afr every time we add fuel the rev's go up. And the rev adjustment is right in. It's also runs on three cylinders on start up till warmed up

Any ideas would be greatly appreciated

Thanks josh

Also, have you done a compression & leak down test on this motor?

You dont have a wideband, you dont have a properly tuneable computer and you are turbocharged, what do you want us to do for you?
