i have an MY00 PPP (prodrive ECU, aftermarket backbox and decat centre)
ive got a manual boost controller and want to up the boost. how high can i go safely?? i have a boost gauge and knocklink on the way.

does upping the boost a few psi make much difference??

cheers

Decat the downpipe to go further. Wait for the gauges.

If you use Optimax and everything behaves you can get a bit more midrange torque out of it.
