Can anyone help ..........

A friend is having problems with his anti-lag set-up:-

With the anti-lag board installed in the P8 ECU, the car is very hard to start and when started, will only run on 2 cylinders, the anti-lag is working because boost is being generated, when switched on, but still only runs on 2

Spec is:-

4x4 Sierra Cosworth
P8 ECU with Collins Anti-Lag Board
Modified throttle elbow with WRC Idle Valve
Greys / T34

Can anyone please help
