Hi Guys, Just wondering if after removing the inlet butterfly & blocking the EGR valve on the 2.8's you need to install a boost controller to lower the boost or minimise spikes.

I'm currently rebuilding my engine, and while i'm waiting for parts to be machined and so on i'm buying and installing the little extra's I want/need.

What kind of pressures are you getting after doing these basic mods, does the boost increase much in the 2.8's after doing this, and what kind of safe levels of boost are you running on your engines if you have up'd it.

Im guessing you only need dawes and needle valve for the 3.0l engines to trick the ECU, you should only need a basic controller for the 2.8's yes?

Thanks,
Shaun...
