Hello to everyone

this is my first topic here in Passionford.com

I have bought a Sierra 4x4 Cosworth last year whit a front damage.

The turbocharger is a T34 with .60 A/R Compressor Housing
/ .63 A/R Turbine Housing, injectors are the blue standart on the 4x4 and the MAP Sensor is a 2 bar (standart MAP).

After the damage i have fitted a bigger Intercooler, but i donn't have the standart amal valve which is brocken.

Is it possible to drive whithout the amal valve and how much boost can the engine run with the T34 and standart MAP (without the amal valve).

In the ECU is a Babyboard with chip and it is written 280PS and something in Itialian language.

How much fuel pressure should be set.
