Well, that's a good point. So I'll just leave it as it is for the moment and put on a -31 actuator to hold boost more efficiently.

But just for the record: How do tuners adjust the fueling? I think KE-Jet does most of the work itself. You only have to make sure that the CO-screw is set to point where it doesn't run too lean and that the fuel distributing part of the metering unit doesn't run out of fuel by keeping an eye on the fuel pressure?

Don't get me wrong here. I'd really like to get the car set up professionaly but Germany isn't the UK. It's really hard to find a decent Ford tuner here and even then they mainly concentrate on Diesel chip tuning

So I really have to do all the stuff by myself, at least trying to learn as much as possible.
