So,.... I was getting pretty high in the rpms lastnight doing donuts. I had replaced the boost controller with another stock boost control from a murker. When im on it hard to about 4,500 rpms not doing donuts the controller works fine. But when im doing burnouts ill get a little higher on the rpms and the overboost buzzer will go off. I was thinking maybe Ford put that there to tell you youre overboosting and that your in too high of rpms. Is it just an overboost notification or rpm and over boost? I replaced the vac lines with 1/4inch fuel line and havnt had any problems. How should i go about fixing it? not doing burnouts is not an option. untill i break something hard to find.

 

The overboost buzzer is an indication that it thinks you are running too much boost. On the SVO I believe it goes off at 17.5psi. My red SVO would only do it if I hammered the s*** out of it in first gear. You could get into the dash and just disconnect it, I spose that would be the easiest. My silver SVO has never buzzed at me.

 

yeah it only happens for me in first gear too, i try not to get on it too hard though.
