Am i right in saying that the maximum boost you can run on OFAC management is 20 psi.

It only allows 9psi unless you chip it and as far as I know it goes up to 14psi or 1bar

Might be wrong though

OFAC has a 2.5bar map sensor
OFAB has a 2bar map sensor

But OFAC is the better system.. If you need help, speak to STU @ Motorsport Developments, he is a god with FORD management

ECU has OFAB or OFAC on the top (by the connector). Also on the bottom sometimes but it can be fiddled with.

OFAB has a suppressor (small black box) on the loom by the ECU connector.

As has already been mentioned, the standard pressure capability of the system is 2bar for OFAB and 2.5bar for Ofac however...

This is NOT whats limiting your boost. Its the small injectors and crap fuel pump, allied to tiny intercooler and an engine bay thats too small for a turbocharged lump.

Boost limits are not your problem im afraid, its the engines capability to accept and deal correctly with it..

Best Regards,
Stu
