Default 94 1.8turbo on mslabs pnp,fuel cut under throttle

Ive finally got it running idle pretty decent after my client installed everything himself with a 2nd hand mslabs pnp wich was configured for a 1.6.
It was mostly a jumper setting on the board wich mslabs helped me figure out.
Been writing a tune and trying out basetunes and tunes others wrote and i cant get my head around why it always cuts fuel under throttle, it does accel enrich but when you hold the throttle it just stalls.
Ive checked crank timing wich was spot on and checked the map line and all vacuumlines.al apear to be good.
I do have a faulty afr controller wich works fine but just doesnt give output signal to the megasquirt.the gauge is being send back to the manufacturer now.
I tought it was cutting fuel because the ms was seeing lowes voltage from afr and therefore was cutting fuel back but now ive tried to disable al o2 sensor interferance from the tune and it stil does this.
i have made a log and i wil upload my last modded tune,i even made a vid while making the log wich i can try to upload if it would be helpfull
