Hi

i have installed the latest GReddy profec boost controller in my cossie powered Mk1 escort.

The engine is running ....
T34.48
siemens 55 injectors
Harvey Gibbs 380bhp chip

I have spoke to Harvey and they say max boost when the amal valve was jetted / fitted was 30psi spike tailing to 26psi

The greddy has setting like
start boost, gain, overboost & set etc

can anyone give me a rough idea as what to set these things to get around the 26psi boost.

Thanks
Tim
