The trick is keeping the RPM's down. You want to row through the gears as fast as you can while keeping the RPM's down, and I'd say below 2K on that engine. You might find a different RPM produces better results though, so try experimenting a little.

Go up slowly. 30 is almost certainly too low, and the door placard is based on comfort, not efficiency or grip. You'll probably find the car hits peak grip at a higher pressure. Go up about 5 PSI at a time, and back off a bit when you notice lower grip.

Edit: I see I'm late to the party.
