If you have the stock dyno, you very well might need a new wastegate as Mike says. When you have your wastegate apart, push the valve on the hot side sideways. If you have play there it's time to replace it.
You can buy a Tial from Brian at Rarlyl8. I'm not sure what he will charge but typically most vendors charge under $500 which is cheap insurance.
I picked up a VDO mechanical boost gauge from Jegs for $35. With fittings, silicone hose and a mount the installation came to $60. I mounted it in the ashtray, which works good since you can tie into the ashtray light to power the light in the gauge.
