Hi all ,

I have an Escort RS cosworth with coil pack ,swedish plenum , ECU P8 and i encounter some problem with the turbo pressure ...

My engine accelerate very slowly and my turbo pressure doesn't exceed 500gr (~7.5psi ) .
Waste Gate Acuator is Ok and there is no leak on pressure loop ...
I wonder if my ECU or a sensor has potenttialy a matter ?

Does anyone have ever meet this mistake ?

Best Regards,

Jérome
